Do-it-yourself repair and replacement of muffler for VAZ 2110, 2111, 2112 + photos, videos

Exhaust system VAZ 2110

Replacing a muffler for a VAZ 2110 or its parts is not work that needs to be done systematically. It is not necessary to change parts of the exhaust system often, in cases where the muffler begins to make noise, its elements burn out, or in the event of a break in the connecting pipes. You can change any part of the muffler with your own hands. The VAZ 2110 exhaust system consists of a reception pipe (another name for pants), a neutralizer, a resonator (additional muffler), and a main muffler.

Replacing the muffler on a VAZ 2110

VAZ 2110 owners are quite lucky, since replacing the muffler is quite simple and does not require special skills or extensive experience. But you definitely need an inspection hole.

The replacement procedure sequence is as follows:

The muffler is connected to the resonator through an O-ring on the pipe flare. Plus, the connection is compressed with a clamp, which consists of two parts.
The clamp must be dismantled, so remove the ring. Since the O-rings used here are graphite, they should not stick to the metal.
Now the old muffler can be dismantled quite easily.
Be sure to check the condition of the suspension rubber bands located on different sides of the muffler body. They often end up stretched or covered with cracks. Rubber bands are quite cheap, so buy new ones and replace the old ones with them.
The new muffler is first mounted on rubber bands, after which it is inserted into the same new graphite sealing ring between the flares. Use a clamp to compress the connection. Ready!

Changing the resonator

It is also advisable to replace the resonator on a VAZ 2110. This is done after changing the muffler.

The work of replacing the resonator is performed in the following sequence:

The resonator is secured to the muffler with a crimp clamp with an O-ring.
It is attached to the neutralizer using a floating flange consisting of two bolts and a flare.
On the opposite side of the element there is a so-called fist.
Removing bolts is often quite difficult. So that you don't have to suffer, just cut them off with a grinder and buy new bolts. This is the simplest solution to the problem.
If you couldn’t get a grinder, use a liquid key. This is a popular product among motorists - WD40 or its analogues. Treat the bolt attachment points with this compound, wait a while, after which the bolts should come off.
After removing the bolts, remove the muffler clamp.
Remove the resonator from the suspension rubber bands. Check the condition of the rubber bands. If they are worn out, replace them with new ones.
Take a new resonator, secure them to rubber and connect them to the muffler so that the pipe leading to the muffler from the resonator is parallel to the ground.
If you notice wear, burrs, or traces of rust on the neutralizer fist, be sure to coat the connection with sealant. Moreover, it must be a high-temperature sealant.
Armed with new bolts and nuts, tighten the catalytic converter and resonator flanges.
The neutralizer is fixed to the resonator with two bolts using a flange connection. The fastening occurs to the states, but there is a receiving pipe, using a spring-loaded connection and two flares. The space between them contains a sealing ring made of graphite or metal asbestos.

Main signs of a faulty or dim headlight

Replacing glass on a headlight on a VAZ 2110
The problem associated with road lighting overtakes every motorist, but what to do in this situation is an individual matter. If, for example, the headlamp begins to work poorly, it can be replaced completely; for this you need to buy sealant and new spare parts, and then, after dismantling the old lamp and applying a new sealant, insert the headlight in the place where the old one was

It is very important to prevent dirt from getting into the connections. The first signs that the car light is not working properly:

Shaking headlights;
Darkening and deterioration of lighting;
Poor adjustment of the light beam;
Malfunction of the hydraulic corrector.

Replacing the neutralizer

As you can see, the exhaust system of the VAZ 2110 car is designed quite standardly, its repair is not difficult even for a motorist with little experience.

When changing the muffler and resonator, it is likely that you may need to replace the converter. This operation is simple and can be done in a few steps.

The neutralizer serves to dampen vibrations from the engine and prevent them from occurring in the exhaust system of the domestically produced VAZ 2110 car.

If it needs to be replaced, it is done like this:

If the old springs and bolts are intact and have no obvious damage, you can continue to use them. They show characteristic signs of wear, be sure to buy new elements.
The ring should be replaced in any case, no matter how well the old one is preserved. If gases begin to leak through the old ring, this will lead to very rapid wear and damage to the converter flare and the exhaust pipe.
After installing the neutralizer, new bolts are put on, they are carefully but firmly tightened. Moreover, the first thing you need to do is tighten the bolts that secure the resonator.

Making your own dual exhaust

If you have the time, materials and necessary technical means, you can make a double exhaust for a VAZ car yourself. You will still have to purchase the main parts of the exhaust system. However, when manufacturing an exhaust system, you can save significantly, at least on the purchase of parts.

Experienced motorists have long developed two main options for manufacturing double exhaust for VAZs.

The first option involves manufacturing an exhaust with different angles of both exhaust pipes. With this option, the second pipe is simply welded from the side into the pipe that comes from the manifold. When the car is idling, the exhaust gases exit the pipes almost uniformly, but at high engine speeds, most of the exhaust exits from a straight pipe that comes from the manifold.

Exhaust with different angles of both exhaust pipes

A different version of the exhaust system will ensure the same amount of exhaust gases from both pipes. In this case, you need to weld two pipes with the same angles and turns at even angles to the pipe that comes from the collector. This can give the structure a more aesthetic appearance.

Exhaust with equal angles of both exhaust pipes

After choosing your exhaust system design, you need to move on to the next step of installing your own dual exhaust design. When installing a self-made structure, problems may arise with pipes deviating from the location of the old holders. But this is not a big problem, since they can be made and installed independently.

Remember that before installing your own exhaust, it must be wrapped with asbestos cord, which will provide thermal insulation. It is extremely necessary in order to avoid fire, since the fuel system is located dangerously close.

As for the installation process, it is identical to the one mentioned above.

To become more familiar with all the nuances of manufacturing and installing dual exhaust on VAZ cars, we bring to your attention a video with a more detailed description.

Replacing pants

The exhaust pipe, also called pants (due to its appearance), is attached to the manifold using studs and nuts. Its fixation with the neutralizer is carried out by a spring-loaded connection.

Remove the exhaust pipe, paying special attention to its attachment to the manifold. Studs are used here, not bolts. They are screwed into the manifold, and connecting nuts are screwed onto them.
If the pin is damaged, it will be extremely difficult to replace it. Therefore, it is important to try to keep the old one intact and safe.
Treat the nuts with WD40, a product we all know. This will allow you to avoid using excessive force and keep the studs intact. If that doesn't work, the studs are drilled out. The process is complex, lengthy, and requires experience and skill.
There is a gasket between the manifold and the pants that needs to be replaced. Also install a new converter o-ring.
Now firmly press the exhaust pipe using the nuts. To do this you will need to compress the gasket.
Then tighten the bolts of the spring-loaded connection with the neutralizer of your VAZ 2110.

As you noticed, there is nothing complicated in this work. Each element is quite easily dismantled and a new one is installed in its place. Just be careful, act carefully and consistently. Plus, of course, do not forget about the importance of the quality of new parts.

Buy only good spare parts that will ensure long-term and efficient service of the exhaust system on your VAZ 2110.

During the operation of a VAZ car, you often have to deal with various noises that come from different parts of the car and indicate that some part will soon fail. The exhaust system is no exception; extraneous noises and sounds when it malfunctions are very characteristic. Their result is the replacement of the VAZ 2110 muffler or other parts through which combustion products are emitted.

Mufflers for cars of the tenth VAZ family: original or cooperative

Original mufflers for VAZ 2110, 2111, 2112 cars are produced at. They are famous for their maximum service life, since the manufacturer does not skimp on thickening the walls and using only high-quality types of metals. In addition, the original mechanisms use a special sound-absorbing material - cotton wool. That is, AvtoVAZAgregat provides owners of domestic cars with completely reliable and durable mufflers. The only drawback is their cost. A new part for the “ten” will cost 2,500 rubles.

In turn, fakes are sold for 1 thousand rubles and even cheaper. However, they are made at home in a garage and have a service life 3–5 times less than the original products. In addition, manufacturers of cooperative “silencers” do not use sound-absorbing wool and do not thicken the walls of the resonators. This means that such an element will not absorb all exhaust noise.

The stainless steel body and wall seal make this muffler almost eternal

Before purchasing a new product, you must make sure that the fastenings are at the same level as on the old one. As a matter of fact, the difference between the models for modifications of the VAZ 2110, 2111 and 2112 lies in the fact that the mounting brackets can be distributed differently. There will be no differences for 8 and 16 valve engines.

In some cases, car enthusiasts buy the first muffler they come across for a VAZ of the tenth family and then use a hammer to adjust the fasteners to the right place. By the way, the procedure does not take even five minutes.

It can also be installed on a car and a device made in Poland by Universal. However, it is recommended to immediately buy a resonator, since the input tube of Universal is 2 centimeters shorter than that of AvtoVAZAgregat and cannot be installed correctly in the system.

Exhaust system diagnostics

To draw a conclusion about the need to replace a particular part of the exhaust system, diagnostics should be performed. You can do this yourself, using a viewing hole or a lift. For novice car enthusiasts, it would be useful to familiarize yourself with the system diagram in order to know the correct name of a particular part and its location.

As you can see from the diagram, the muffler is the last link in the flue gas emission system. Its main task is easy to determine from the name: to muffle the loud sound of the engine, bursting from the cylinders along with the products of fuel combustion. The muffler and the previous link in the chain - the resonator - most often fail and must be repaired or replaced.

The appearance of exhaust pipe malfunctions is characterized by a whole range of different sounds, from humming and growling to unpleasant rattling. They are united by one feature: sounds come from under the bottom of the car, its middle and rear parts. It is worth noting that not all sounds indicate a direct malfunction; sometimes it is enough to inspect the car from below and remove the cause of the noise. Recommendations for diagnosing exhaust system faults.

After the car is placed on the inspection pit, it is necessary to prevent it from rolling, since diagnostics will have to be performed at idle engine speed while in the pit. Therefore, if you are not confident in the hand brake of the VAZ 2110, then it is better to place stops under the wheels. Start the engine and go down into the inspection hole.
It happens that traces of a muffler burnout are immediately noticeable, and a growling sound is heard from the hole. But the hole is not always located on the bottom of the assembly; it can be located on the top and on the sides, especially in those places where pipes are welded to the muffler. It is necessary to carefully inspect the unit and identify the location of the gas breakthrough.

The nasty rattling sound characteristic of VAZ cars coming from the muffler indicates that you need to prepare to replace it. The noise comes from a burnt-out partition, which, due to vibration, dangles inside the case and knocks on the walls. In this case, no breakthrough of flue gases is observed, the malfunction is not fatal, and the operation of the car can be continued. But this sign indicates that the muffler is nearing the end of its service life.
Stretched or torn suspension rubber bands of the exhaust pipe allow it to dangle with a large amplitude, hitting elements of the car body. This is characterized by dull knocking sounds; being in the inspection hole, it is easy to determine their source. Such a small malfunction is not difficult to fix; you just need to replace the rubber bands.
A hum with vibration transmitted to the car body indicates that the exhaust pipe is in contact with the bottom directly or through a foreign object. This may be the result of impact and deformation of exhaust system components. In this case, you need to take measures to straighten the pipe so that there is a gap of at least 1 cm between it and the body parts. Another reason is dirt that has accumulated between the pipe and the bottom after driving on a wet dirt road. The issue can be resolved by simply cleaning the bottom from dirt.
After driving on various forest or field roads, it is recommended to always inspect the underbody of the vehicle for the presence of stuck foreign objects, such as branches. A stick stuck between the exhaust system pipe and the underbody element very well transfers the hum and vibration from the engine directly into the interior of the car.

Features of operation and types of mufflers

How to change pipes on a VAZ-2110 stove

There are two types of mufflers used in modern cars: resonant and direct-flow. Both can be installed in conjunction with a resonator (pre-silencer). In some cases, a straight-through design can replace a front muffler.

Resonator device

Structurally, the muffler resonator, which is also called a flame arrester, is a perforated pipe located in a sealed housing, divided into several chambers. It consists of the following elements:

body (has a cylindrical shape);
thermal insulation layer (exhaust gases have a very high temperature);
blind partition (to turn the flow of gases);
perforated pipe;
throttle (allows you to change the cross-section of the exhaust gas flow).

Resonant muffler design

Unlike the preliminary muffler, the main resonant muffler is more complex. It consists of several perforated pipes installed in a common housing, which are separated by partitions and located on different axes (see Fig. Silencer in section):

front tube with perforation;
rear tube with perforation;
inlet pipe;
anterior partition;
middle septum;
posterior septum;
exhaust pipe;
body (oval section).

Thus, a resonant muffler uses all types of transformation of sound waves of various frequencies.

Features of a direct-flow muffler

The main disadvantage of a resonant muffler is the effect of creating back pressure, which occurs as a result of redirecting the flow of exhaust gases (when it collides with partitions). In this regard, many motorists tune the exhaust system by installing a direct-flow muffler.

Direct flow muffler

Structurally, the direct-flow muffler consists of the following elements:

sealed housing;
exhaust and inlet pipe;
perforated pipe;
soundproofing material - fiberglass is most often used, which is resistant to high temperatures and has good sound-absorbing properties.

In practice, a straight-through muffler has the following operating principle: one perforated pipe passes through all chambers. Thus, there is no noise suppression by changing the direction and cross-section of the gas flow, and noise suppression is realized solely through interference and absorption.

Due to the unhindered passage of the exhaust through the direct-flow muffler, the resulting back pressure is very low. However, in practice this does not provide a large increase in power (from 3% to 7%). On the other hand, the car has a characteristic sports car sound, since the noise-absorbing technology present in it only eliminates high frequencies.

The comfort of the driver, passengers and pedestrians depends on how the muffler works. So, during prolonged use, increased noise can cause serious inconvenience. Today, installing a direct-flow muffler in a structure for a car moving within city limits is an administrative violation that threatens with fines and an order to dismantle the device. This is due to exceeding the noise limits specified by the standards.

The operation of the engine in vehicles, if we talk about internal combustion engines, is associated with the production of quite loud noise. But the driver, his passengers, and people on the street practically do not hear this noise effect.

This was not always the case. The first cars running on internal combustion engines were very noisy and created a lot of smoke, and therefore this became a real problem. But after some time they came up with a solution.

Every modern car is necessarily equipped with a muffler. Already from the name it becomes obvious that the main function of mufflers is to dampen and suppress noise and sounds arising from a running engine.

The exhaust system is quite complex, despite the apparent simplicity of its functions. It consists of several elements, one of which is a resonator. Car enthusiasts have questions regarding it. They are interested in what it is, why it is installed and what tasks it performs in the operation of the exhaust system and the entire car.

How can I fix the problem?

So, the place of gas breakthrough through the muffler has been detected, you just need to make a decision about replacement or try to repair the unit. Often the holes in the body are small, and in this case it is not always advisable to buy a new muffler. It is necessary to remove the unit from the car and show it to a welding specialist, who will tell you whether it can be repaired.

The craftsman will cut out the rotten part of the body, shake out the remains of the burnt partitions from the inside and apply a patch of new metal. Fistulas that occur at the points where the pipe is connected to the body must also be eliminated by welding. The only caveat is that these repairs solve the problem only temporarily. Such a muffler will not serve for a long time, and it may perform its function poorly; due to the lack of partitions, the sound will break through.

If it is decided that the muffler needs to be replaced, then you need to select and purchase it. New elements are made of black or stainless steel, so the choice is limited. The latter last much longer than black ones, but their cost is higher. In addition, welding work in case of repair of a stainless steel body will be more expensive. When purchasing a new muffler, it is worth purchasing a new set of suspension rubber bands, as well as a graphite O-ring. It is installed at the junction of the resonator and muffler pipes.

The exhaust system of the VAZ-2110 is designed for cleaning exhaust gases. The components included in it have a fairly long service life. But since the entire system is constantly experiencing temperature overloads, the metal gets tired, cracks and burnouts appear. Repairing the exhaust system yourself is quite simple. This allows owners of the “ten” to significantly save on maintenance. The design of the exhaust system includes: the main muffler, neutralizer, exhaust pipe and resonator.

Description of individual components

Muffler for Priora

To make the structure of such an element as the discharge system clearer, it is necessary to give a detailed description of all components:

Neutralizer. A unit designed for effective purification and suppression of emissions of harmful substances into the environment. When driving, a car produces substances such as non-combustible hydrocarbons, oxide compounds of nitrogen and carbon. The work of this system is aimed at eliminating them. The design itself is a combination of two ceramic-type components. The surface of these components is coated with special afterburning catalysts, which include rhodium, palladium and platinum. These substances make it possible to purify exhaust gases emitted into the environment by almost 100%;
Lambda probe. It is a special sensor whose task is to control the composition and amount of fuel that enters the engine. The lambda probe thereby controls the purifier. If the lambda probe does not work properly, then the entire output assembly will quickly become unusable, after which it will have to be replaced;
Reception pipe. Designed for forced removal of exhaust gases from the cylinders of a power unit. The pipe is made of stainless steel, and its fastening to the collector is carried out using special pins, of which there are four in total. The studs guarantee reliable fastening of the two outlet pipes and the element. In order to combine the exhaust pipe and the neutralizer, as well as an additional muffler, hinged fasteners are used;
An exhaust manifold. A component that is cast from pure cast iron. The manifold is secured with four studs in the exhaust pipe. Heat-resistant gaskets reinforced with metal are installed between the manifold and cylinder heads.
Silencers. Necessary for effectively suppressing the exhaust rate of burnt gases. This is necessary in order to significantly reduce the noise level in a type of transport such as the VAZ 2110. The distribution device in this part of the unit is carried out as follows: the additional one is followed by the main one. These two components are connected to each other by clamps and sealing rings and are covered with a special casing on top.

Replacing a muffler on a VAZ 2108/2109 has its own nuances, which can be found here: https://vazweb.ru/desyatka/vyhlop/zamena-glushitelya-vaz-2109.html

Typical exhaust system faults

Be sure to verify that there are any problems with the exhaust system before starting any repairs. And identify the node that has become unusable. Any breakdown reveals itself with the following signs:

Broken connecting pipes. As a result, the integrity of the entire system is compromised and exhaust gases are not properly purified.
Burnouts on the elements of the main muffler and resonator. This leads to the fact that the exhaust gases are not cleaned, and an extraneous sound appears when the engine is running.
Strong noises appear from the exhaust system and the main muffler, indicating that there is damage.

If small cracks appear in the VAZ-2110 exhaust system (8-valve injector), then in the early stages they can be healed using sealants. This measure will increase the service life of the elements slightly, by no more than one year.

How to reduce exhaust noise

A sound wave can travel in space much faster than gases, therefore, in the design of a muffler, its noise reduction circuit is of great importance.
Physical vibrations from sound waves are transmitted to the walls of the exhaust system, and its design is made in such a way that it converts the sound wave into thermal energy, which the exhaust pipe, like a radiator, releases to the atmosphere. Reducing the noise level of a muffler cannot be achieved without creating some kind of resistance to the exhaust gases, as a result of which part of the engine power, quite insignificant, is spent on overcoming this resistance. To minimize the power loss that noise reduction inevitably leads to, a direct-flow muffler has been developed.

It has a minimum of partitions, does not interfere so much with the passage of exhaust gases and reduce their speed, which is why it sounds completely different.

How to remove the main muffler on a ten

As with most front-wheel drive models, replacing the exhaust system of the VAZ-2110 is quite simple. You do not need any special skills, extensive experience, or special tools.

But it is advisable to carry out all work on an inspection hole or overpass. The sequence of work is as follows:

The connection between the resonator and the muffler is made using flared pipes and an O-ring. This connection is crimped with a metal clamp, which consists of two halves and bolts.
First of all, dismantle the clamp; to do this, unscrew the nuts from the bolts using two 13mm wrenches and remove the O-ring. On cars of the tenth family, sealing rings made of graphite are used. Therefore, they do not stick to the surface of the pipe.
Remove the old main muffler from the rubber hangers.

When to change the resonator, and which resonator to choose?

A resonator is a part of a car’s exhaust system, which is responsible for partial compensation of the sound wave that appears when the fuel mixture detonates in the engine combustion chamber.
Not every car has resonators; some small cars can be equipped without it at the factory, but in most cases it is installed in the car. This part of the exhaust system is responsible for damping the sound wave corresponding to the low-frequency range. The resonator works in tandem with a muffler, due to which it is possible to achieve relatively quiet engine operation, even at high speeds. The resonator is especially effective at compensating for resonant sound waves.

Do I need to change the resonator?

The resonator is subject to a large temperature and vibration load, which leads to its failure after some time.
In essence, the resonator, like the muffler, is a consumable component of the car. The validity period depends on the quality of production. Over time, under the influence of high temperature and corrosion processes, aging of the resonator metal occurs. As a result, the steel burns out and the resonator loses its seal. Sometimes the internal parts of the resonator (the filling of the can) are the first to fail, then the resonator may become clogged. This is often the answer to the question of why the resonator is ringing or making a humming sound.

Installing a new muffler

The cost of these rubber bands is small, they are available in any store. Next you need to do the following:

Install the new main muffler onto the rubber hangers.
Insert a graphite O-ring between the pipe flares.
Place the clamp in place and tighten the nuts using 13mm wrenches.

At this point, the repair of the main muffler of the VAZ-2110 exhaust system (8 valves) is completed. Start the engine and check the muffler operation. There should be virtually no sound from the exhaust pipe. The motor will run clean and smooth.

Dual Exhaust Installation Steps

First of all, you need to remove the old muffler.
Afterwards, you should hang the right part of the new muffler on the right side of the car (previously placed on a lift), while using the existing cushions. In this case, the left part does not need to be fastened; you just need to connect the muffler to the resonator using a clamp and seals.
Next, you need to connect the left part of the muffler to the main part through the pipes. In this case, it is necessary to take into account the location of the fastening rod, and it is also necessary to calculate the place where the holders in the form of brackets will be placed.
It is necessary to use a drill to make two holes with a diameter of 1.5 mm in the spar. These holes can attach a holder, which is screwed with self-tapping screws.
The completed operations allow you to move on to attaching the main left part. Fastening is carried out by inserting the muffler cushion directly into the bracket-shaped holder; the exhaust rod is also inserted into the cushion.
The opposite side of the muffler is secured using O-ring clamps. This fastening should not be too tight.
All the work done allows us to move on to the process of adjusting and establishing symmetry between the two exhaust pipe tips. Initially, loosely tightening the connections will allow the installation to be fine-tuned.

How to remove the resonator

The resonator needs to be changed only after a new muffler has been installed. The sequence of work aimed at dismantling the device:

The resonator is secured using a crimp-type clamp and an O-ring.
The connection to the neutralizer is made using a floating flange, which consists of flared pipes and two bolts.
The fist is located on the opposite side of the resonator.

The work must be carried out on a cooled engine.

Quite often it is not possible to unscrew the bolts, so to make the work easier, you just need to cut them off using a grinder. Be sure to install new bolts during reassembly. If you don’t have a grinder at hand, then you need to use a penetrating lubricant, for example, WD-40. Apply this composition to all threaded connections, then wait 20-30 minutes.

Unscrew all the bolts and remove the clamps on the resonator. After this, you need to remove the old resonator from the rubber suspensions. Be sure to evaluate the condition of all rubber products. If they show signs of wear, install new ones during reassembly.

Resonator installation

In the VAZ-2110 exhaust system (16-valve injector), work is performed in exactly the same way as on 8-valve engines. The procedure is as follows:

The new resonator must be mounted on rubber hangers and connected to the muffler. Moreover, it is necessary that the pipe from the resonator be strictly parallel to the ground.
If the neutralizer has wear, rust, or burrs, the connection must be lubricated with high-temperature sealant. This will ensure a high-quality connection of the exhaust system components.
Tighten the resonator and catalytic converter flanges using only new nuts and bolts.
The resonator is fastened to the neutralizer using two bolts and flanges. Moreover, the pipe is secured to the pants using a spring connection and flaring. An O-ring made of metal asbestos or graphite is installed inside.

This completes the replacement of the resonator; repairs present no difficulties. All work can be done independently, you just need an inspection hole or overpass.

Problems with the resonator

Like any part, a car resonator periodically fails. After all, it passes through exhaust gases having a temperature of several hundred degrees Celsius. And in combination with the aggressive chemical elements contained in the escaping gas mixture, this leads to gradual burning of the metal parts of the system.

The main signs of resonator failure are:

Deterioration of the muffler and exhaust system. This is manifested by increased sound coming from the exhaust pipe, especially low frequency sounds (roar).
The appearance of exhaust gases from under the bottom of the car. This is a clear sign of depressurization of the resonator or other parts of the gas exhaust system.
The presence of a characteristic rattling metallic sound from the resonator. It appears due to the fact that one (or more) of the internal components of the device burns out. Usually in such cases he “hangs out” or breaks away and rumbles in one of the cells.
Significant drop in engine power. Due to a malfunction, the throughput of the resonator decreases significantly, so it dampens uneven pulsations of exhaust gases worse or not at all. And this gives feedback on the deterioration of the power unit.

If you encounter one or more of the above signs of a resonator malfunction, you need to inspect its operation as quickly as possible.

How to check the catalyst?

Engine power depends on the condition of the catalyst. If there are characteristic symptoms of a breakdown, you should definitely check it. This can be done in light (by dismantling) and for back pressure or CO content without removing Read more

Replacing the VAZ 2110 resonator

Repairing the exhaust system or replacing the muffler on a VAZ 2110 most often involves replacing the resonator, since welding does not take long to solve the problem of burnout. The main task is to quickly remove the resonator Read more

How to remove the neutralizer

The VAZ-2110 exhaust system is standard for all cars. Almost the same design is used on nines, sevens, and even foreign cars. Even a motorist with very little experience can repair all elements of the system. If you have already decided to change the resonator and muffler, then it is also advisable to install a new neutralizer. The neutralizer is necessary to dampen the vibration coming from the car engine. This is a device that mechanically separates the muffler resonator and the exhaust pipe.

Replacement is carried out as follows:

If there is no damage to the springs and bolts, they can be reused. If there is wear, you need to purchase new elements.
The ring is replaced in any case, even if it is in almost perfect condition. If this ring begins to allow exhaust gases to pass through, damage to the flaring of the exhaust pipe and the converter will occur.
Unscrew all the bolts used to secure it. They must first be treated with a penetrating lubricant.

Device

The muffler is part of the exhaust system. Its complete structure is as follows:

an exhaust manifold. Through it, gases penetrate into the “pants”;
“pants” (reception pipe). They are separated from the manifold by a special gasket that holds the mount hermetically;
pipe. Which is attached to the gearbox using a bracket;
additional resonators. They are attached to the main muffler and exhaust pipe with clamps. They form an additional muffler;
main muffler. Fixed to the bottom of the car to prevent the transfer of vibrations to the body;
exhaust pipe.

The VAZ 2107 (injector) is equipped with a part that is shorter than that of the 2104 due to the length of the body itself.

Installation of a new neutralizer

If you decide to modify your car, you can install the Stinger exhaust system on the VAZ-2110. It is more reliable and advanced than stock.

All work is carried out the same way. The neutralizer is installed as follows:

Install the neutralizer, and then put on the bolts. This must be done very carefully, making half a turn, no more.
When tightening, you must first tighten the bolts that secure the neutralizer to the resonator. The last to be tightened are the bolts securing the converter to the exhaust pipe.

Removing the exhaust pipe

Most drivers call the exhaust pipe “pants”, since the element is very similar to this item of clothing. It is secured to the exhaust manifold using bronze nuts and studs. The trousers are attached to the neutralizer using a spring-loaded connection. There is a gasket between the exhaust manifold and the pants to prevent gases from leaking.

Dismantling the intake pipe is carried out as follows:

Using a 13mm wrench, you need to unscrew the nuts that secure it to the exhaust manifold. If there are metal plates with bent edges under the nuts, they must be bent. Please note that the connection uses studs that are screwed directly into the manifold.
If the stud is damaged, replacement is quite problematic. Therefore, it is necessary to carry out all work carefully to keep the threaded connection intact.
Be sure to allow the engine to cool before starting work, then apply penetrating lubricant to all threaded connections. With these simple steps, you won't have to use too much force, which will save your studs. If you break a pin, it will need to be drilled out. Before this, the exhaust manifold must be removed. Moreover, if you damage the exhaust manifold, replacing it will cost you a pretty penny. The cost of a new one is more than 2000 rubles.
After unscrewing all the nuts, it is necessary to move the exhaust pipe to the side and remove the gasket.
Unscrew the bolts that connect the exhaust pipe to the converter.

This completes the dismantling of the exhaust pipe of the VAZ-2110 exhaust system.

An exhaust manifold

The exhaust manifold is attached to the cylinder head directly with studs through a heat-resistant reinforced gasket. It is made of heat-resistant cast iron according to scheme 4-2. The collector is constantly subject to alterations from tuning studios, which replace the factory circuit with a wide variety of configurations and mounting options. It must be said that replacing the standard circuit, and especially replacing cast iron with steel, cannot bring anything good to the car.

The exhaust manifold is made of heat-resistant cast iron

Unless you are designing a narrow-profile car for competition. Moreover, for each discipline of motor sports, the exhaust manifold is configured separately and has some nuances in the design, which 90% of tuning studios have no idea about. Especially their customers. In most cases, the main focus is on the appearance of the pipe, but how it will work there is, by and large, all the same.

It must be said that the exhaust manifold is a rather important part and making it from steel, even the most heat-resistant, is a very questionable undertaking if the car will be used under normal conditions, and not just on the track or in rally raids. The collector temperature in operating mode can reach 1000 degrees. The cast iron is there for good reason and not at all to weigh down the engine structure. Any steel will burn out quite quickly under high load conditions, so before you buy an upgraded exhaust manifold made of super-Japanese steel, it would be worth thinking about the feasibility of such a replacement. Most of the top ten, thank God, do not participate in the world circuit racing championships; they simply have nothing to do there. Therefore, it would be more logical to correlate the rather modest capabilities of the VAZ 2110 engine with the level and quality of exhaust system tuning.

The exhaust manifold lasts almost forever and burns out in rare cases, and then due to a manufacturing defect. As part of improving the manifold with more effective methods, we would recommend that instead of installing thin-walled beautiful pipes of space configurations, simply pay attention to the mating of the exhaust ports of the cylinder head and the manifold holes. The fact is that the whole essence of tuning the exhaust system comes down, of course, to an amazing increase in power by reducing the resistance to exhaust gases. So it is precisely at this interface that the first additional power losses occur - at the junction of the manifold and the cylinder head. If the exhaust window and the manifold opening have even the slightest difference in size or level, parasitic vortices are formed that prevent the exhaust gases from escaping. If this is the case, after the collector you can even hang platinum direct flows with Swarovski diamonds, there will be no sense. If we are, of course, talking about saving power.

Installing a new exhaust pipe

All work is done in reverse order. But there are several features that you definitely need to know:

Install a new exhaust pipe.
A new gasket needs to be installed between the exhaust manifold and the pants.
Be sure to install a new O-ring between the neutralizer and the pants.
Tighten the nuts on the exhaust manifold studs. Tighten them evenly in a crisscross pattern.
Tighten the bolts that are on the spring-loaded connection to the converter.

This completes the repair of the exhaust system. The sound will be muffled as much as possible, the car will become almost silent. It is advisable to lubricate the new gasket with a CV joint type compound. This will improve the seal.

The exhaust system of any car constantly suffers from hot caustic gases, dust, dirt, moisture, impacts, and the VAZ 2110 muffler is no exception. Attempts to repair by applying to through holes help only for a short time, and therefore, you have to think about a major overhaul with replacement.

Muffler device for VAZ 2110

On the “ten” the entire exhaust system consists of separate components:

exhaust pipe (“pants”);
neutralizer;
Lambda probe;
additional muffler (resonator);
main muffler.

The most vulnerable and most often in need of repair are. It is not difficult even for a novice car enthusiast to understand the procedure for replacing these parts. Let's try to figure it out together how to gain experience in auto repair and save money.

Replacing the main muffler VAZ 2110

The main signs indicating the need to replace the muffler “can” are the appearance of pockets of through corrosion, fractures of the body and pipes, and severe deformation from impacts. Work should begin when the car is installed on the inspection hole. For a successful start and completion of the operation, a standard set and overalls are sufficient, since the bottom of the car is not the cleanest place.

Muffler 2110 is attached to the bottom of the car on brackets through hanging rubber bands, and to the resonator pipe by means of a bolted connection of two halves of clamps, tightening the flared ends.

Dismantling and installation of the device is carried out in the following sequence:

the bolts that tighten the clamp are unscrewed (often, due to severe corrosion, the bolts cannot be unscrewed and then they are cut off with a grinder. It is recommended to install a new clamp and bolts each time during repairs);
the graphite sealing ring is removed;
the muffler is removed from the suspension rubber bands;
if necessary, the rubber bands are replaced with new ones (experts recommend doing this);
the new muffler is suspended;
a graphite seal is installed at the junction of the pipes;
a clamp is put on, the parts of which are tightened with bolts.

basic information

The muffler of a VAZ car always receives increased attention, because its main task is to reduce the noise level, which is important.
First, let's look at how the pre-muffler, or as it is also called the resonator, works in a VAZ car. The resonator is considered to be a medium type of muffler, which is located in the middle of the exhaust system. So, the pre-muffler consists of the following main elements:

Throttle;
Frame;
Blind barrier;
Thermal insulation;
Perforated tube.

Now let's look at the design of this part of the transport:

Frame;
Rear barrier;
Middle obstacle;
Front perforated tube;
Rear perforated tube;
Inlet pipe;
Exhaust pipe.

VAZ muffler design

What are the design features of a direct-flow muffler? The main element of this type of muffler is a perforated tube. With the help of perforation, the combustion products that enter the muffler expand quite effectively in its body. Thanks to these actions, the removal of combustion products is accelerated

It is worth paying attention to the fact that high-quality tuning can account for more than eighty percent of a straight tube. This means that when using the presented type of muffler, the level of exhaust system resistance will be about ten percent, and this is much more than without it.

Independent replacement of the main and additional muffler

The exhaust system of every vehicle regularly suffers from the accumulation of dirt, dust, moisture, corrosive and hot gases, as well as impacts. Moreover, applying patches to through holes will help solve the problem only for a certain period of time, and in the end, one way or another, a complete replacement will have to be made.

The exhaust system of a VAZ car can be subject to such main factors of destruction as:

Heating the structure to high temperatures;
Internal corrosion;
External corrosion;
Beats;
Various damages and deformations;
Constant vibration;
Frequent changes in temperature conditions, from the heating process to rapid cooling;
There are no effective means of protecting metal structural elements;
Pollution;
The influence of abrasive particles falling from the roadway;

The most vulnerable point of the exhaust system, which requires regular monitoring, is the muffler. Let's try to figure out how to replace the main muffler. The main signs that indicate the need to replace the housing of this device:

Areas of through corrosion;
Pipe fractures;
Fractures of the hull;
Deformation.

So, the replacement algorithm:

Unscrew the bolts that hold the clamp halves together;
Remove the graphite O-rings;
Remove the part from the hanging rubber bands. If such a need arises, you need to replace the hanging rubber bands.
Hang a new one;
Install a graphite seal at the junction of the pipes;
Put on the clamp;
Tighten the clamp halves using bolts.

Now we move on to considering the replacement of the additional muffler. Additional mufflers are not attached to the underbody of the vehicle. They are connected to the inlet pipes using clamps.

So, the replacement algorithm:

Remove the main muffler;
Loosen the clamp nut slightly;
Using a screwdriver, spread the clamp and move it along the tube;
Unscrew and remove them from the drain manifold tube.

The car should not only drive well, but also sound great. A good car is beautiful in all respects, and its beauty partly depends on the sounds that the equipment makes. The spectacular sound of a closed door, with a noble low overtone, the muffled clicking of the turn relay, the dense rustle of the headwind at a speed of 180 km/h. And, of course, the exhaust sound. It is the muffler that forms the first impression of the car and we will talk about the muffler today.
