Priora exhaust pipe diameter

Problems with the exhaust system send drivers to maintenance. Whatever muffler you install, it will burn out over time - no matter how much it costs. The muffler, also known as the exhaust, of a Priora sedan, hatchback, and station wagon is the same and also burns out over time. Of course, the main muffler on the Priora is better made of stainless steel - despite the fact that it is more expensive. The price for example is STT - 4950 rubles, and Mute stainless steel - 4500 rubles, Stinger (stinger) - 4100 rubles. Replacing a muffler, although not a common thing, car enthusiast forums are regularly updated with fresh articles devoted to the problems of the Lada Priora car exhaust, operation, and replacement of the middle part of the car exhaust system, clearly indicating the relevance of the issue. The exhaust system is the exhalation for a car - it is important, just like the intake system. In this article we have collected most of the most pressing consumer questions.

Standard muffler - article number and price

The VAZ 2170 Priora is equipped by the factory with spare part item number 2170-120010. Made of light sheet steel with a thickness of 0.8-1.1 mm. Connecting inlet pipe with a diameter of 48mm. Inside the muffler chamber (an oval tank - popularly known as a barrel) there is a series of parallel chambers for the last stage of dampening the force of the sound wave of the exhaust gases. The exhaust pipe allows you to install different types of muffler attachments to add uniqueness and change the sound characteristics of your car's exhaust. The price of such a standard muffler is in the range of 1200-1600 rubles. Of course, you can go much further.

What are the advantages of dual exhaust?

Even if the engine on the Priora remains factory, installing a dual exhaust pipe allows you to:

accelerate the removal of fuel combustion products, which leads to an increase in engine power;
reduce noise;
give the vehicle a more sporty look;
improve the sound of the installation.

It is worth noting that there are only two options allowing a car owner who wants to refine the appearance of his Priora to install a double exhaust:

buy a ready-made twin muffler in specialized stores, which are now available in almost every city in Russia;
make it yourself.

It should be recognized that the first scenario requires quite serious financial investments, but the second will cost much less, since the result is achieved rather through accuracy and painstakingness.

Main malfunctions of the Lada Priora muffler

The main reasons for replacing or repairing this part of the exhaust system are often burnout, rupture of the tank with loud bangs inside, loss of integrity, and deformation of structural parts. Loud roar when operating at high speeds, impacts on the body. An important factor in the failure of the Lada Priora muffler is metal corrosion, which occurs when the protective coating is lost as a result of overheating and condensation of water vapor on the walls.

Fluid in the muffler

accumulation of liquid in the cavity of the barrel or, as experienced car enthusiasts joke, “drips from the end”) is a fairly common phenomenon. It is important to find out what kind of liquid collects inside. Often the reason for this is water condensation formed from the difference in the operating temperature of the unit and the external environment. It has a negative effect on models made of iron-zinc steel that are poorly protected against corrosion. Models made of steel with a share of aluminum or stainless steel are less susceptible to this influence. Many people find a way out by drilling a drainage hole in the corner of the tank. If you find antifreeze or antifreeze in the liquid, it’s time to sound the alarm. Malfunction in the tightness of the cooling system of the car engine (loss of integrity, wear of the cylinder head gasket, depressurization of the cylinder block). You should immediately check the operation of the cooling system and eliminate the cause to avoid further negative consequences.

Loud roar at revs

The sound of the exhaust gases changes when the engine speed reaches over 3000. The reason for this behavior is often the burnout of the partitions inside the resonator, the middle part of the exhaust system, or a clogged exhaust catalyst. Loss of joint density, structural integrity as a result of corrosion, burnout of individual elements, cracks at the joints of parts. All this indicates the end of the service life of the spare part. The only reliable solution is to replace the faulty system unit. Eliminating these defects with a hammer and a welding machine is a temporary solution.

Roar, shooting, condensation and other reasons to look under the car

It's easy to spot muffler problems. It is difficult not to notice extraneous sounds coming from under the car, or a sharp change in the tone and volume of the response to pressing the gas. It is not uncommon to notice fluid leaking or even splashing from the exhaust pipe. All these are signs of malfunctions, but do they all indicate problems in the exhaust system?

Fluid in the muffler

Fluid dripping from the exhaust pipe is a common occurrence. However, it is worth distinguishing what kind of liquid it is. If it's water, there's nothing wrong with it. When the ambient temperature changes, moisture from the air condenses on the surfaces of the muffler. If a steel muffler is used, this can lead to corrosion, but usually the Priora exhaust system uses aluminized steel or stainless steel, which means that damage from water will be minimal. In cases of heavy accumulation of water, experienced motorists usually drill a drainage hole in the “barrel” of the muffler.

If there is excessive accumulation of water in the muffler, in winter you may encounter icing of the exhaust pipe

If antifreeze drips from the exhaust pipe, the fault should be looked for not in the muffler, but in the engine. The reason may be wear of the cylinder head gasket, as well as depressurization of the block itself. Antifreeze in the exhaust pipe is a symptom of serious problems, and if it is detected, you should immediately diagnose the engine.

Pops and shots from the exhaust pipe

Popping noises coming from the muffler indicate a malfunction. However, this is also a malfunction of the engine, not the exhaust system. Shots or pops from the exhaust pipe indicate that the mixture of air and gasoline does not burn out in the cylinder block, which means that when you hear them, you should check the spark plugs and spark plug wires, as well as the serviceability of the gas distribution mechanism. Problems with combustion of the mixture are not a symptom of a muffler failure, but they can be its cause.

Video: this is what pops from the muffler sound like

Knocking from under the car

A knocking sound from under the bottom of the car while driving or rattling from vibrations is an unpleasant phenomenon. The muffler may touch the gas tank or the underbody. There are several possible reasons for this.

First of all, check the rubber muffler hangers. Their wear leads to loosening of the entire exhaust system. These mounts are sold at most auto parts stores. Their price usually does not exceed 100 rubles per piece. Replace the suspension with new ones and the knocking will stop.
It is worth checking whether the clamp connecting the main muffler and the additional muffler is loose. If necessary, replace the fastening bolts and nuts. For replacement, it is best to use fasteners made of heat-resistant materials.
Using the wrong model of muffler with pipe bends that differ from the original spare part can lead to contact between the exhaust pipe and various components of the car: the body, the gas tank and even the suspension. Be careful when choosing a muffler.

Lowered the car - the muffler is knocking

When installing a short-travel suspension on a Priora, tuning enthusiasts often encounter a situation where the suspension beam, which has moved closer to the body, begins to touch the muffler. This problem can be solved by replacing the muffler hangers with new ones of a more suitable shape.

Loud roar at revs

If a vehicle's exhaust system loses its seal, it cannot effectively reduce the volume of exhaust emissions. In this case, the exhaust often takes on a “pseudo-sports” sound. Therefore, if the muffler growls, you should look for a gap in it. It can be on the muffler body or on the pipes. It makes sense to check the connections and their fastenings. If the metal from which the muffler is made is of low quality, the exhaust pipe may burn out due to temperature. Time, corrosion and the quality of domestic roads cause damage to the exhaust system.

Pressure and temperature can cause holes

A burnt or broken muffler is easiest to replace. If depressurization occurs at the joints, you can limit yourself to replacing the sealing ring and the necessary fasteners.

Manufacturers of mufflers and prices of analogues for Priora

The choice of Priora mufflers available to consumers is huge. Many of them differ in the name of the manufacturer's plant. Let's look at the main ones that differ in production method and materials:

Muffler made of steel with a large admixture of aluminum (Lada-Image, EDEX, PHOENIX, etc.), resistant to corrosion, suitable for all body types. Its disadvantage: the presence of welding seams in the design of the part. Price – from 2500 rub;
The sunset type of production (Phobos, NAAZ, Avtokomplekt, etc.) has the main advantage that the part is produced without welding technologies or the use of stainless steel, so it has an increased service life. The price of such a “stray” is from 3000 rubles;
Budget muffler (“VVV Tolyatti”) uses iron-zinc steel in production, is short-lived, suffers greatly from corrosion, and wears out quickly. The only plus is the price of the spare part is approximately 1400 rubles;
A separate type is stinger (spider) forward flow exhaust systems (“MUTE”? “StinGer-auto”, etc.). Advantages - a slight increase in vehicle traction, choice of high-quality materials in manufacturing, long service life.

Prices vary greatly depending on the manufacturer, from 4500 rubles. Remember, it’s better to buy one good exhaust than two bad ones, and your Priora will be satisfied.

Mufflers VAZ 2101-2107 (Classic)

Silencers for domestic classics come in 3 types:

Muffler for a classic sedan body assembled by AvtoVAZ (VAZ 2101, 2103, 2105, 2106, 2107) stamped and welded
Muffler for a classic station wagon assembled by AvtoVAZ (VAZ 2102, 2104) stamped and welded
Muffler for classic IZhavto assembly (VAZ 2104, 2106, 2107)

Despite the fact that the length of the classic sedan and station wagon is approximately the same, their mufflers are slightly different. The main difference here is not the length of the exhaust pipe, but the bend of the pipe that goes around the bridge (unfortunately, this is almost invisible in the photo). Also, about the first 2 types of mufflers, it must be said that they can be presented on the market in 2 types of production:

Stamp welding is a production method in which two metal parts of the muffler can are stamped, then welded together and the whole thing is welded to the pipe.
Sundown is a manufacturing method in which a sheet of metal is taken and wrapped around the muffler entrails.

Historically, mufflers were previously manufactured only by the stamp-welded method. Then bam, nano technology! A seaming method has appeared, which is cheaper to produce and more reliable compared to the stamp-welded method, because One weld is better than a muffler welded all over. In this case, it does not matter what method the muffler is made of - they fit like originals, both stamped and welded. However, keep in mind that the original muffler for classics is only stamped and welded, because The factory makes them only using the old method.

The presence of the 3rd type of muffler is explained by the fact that when the production of the VAZ classic was completely transferred to Izhevsk, they decided to install their own exhaust system, the production of which had already been established.

From the classics, let's move on to front-wheel drive VAZ cars, where the above-mentioned rule applies 100%: “The longer the body, the longer the exhaust pipe of the muffler.” But there are nuances here too.

Removal and installation of the main muffler of the Lada Priora

Replacing the muffler on a Priora yourself is possible within the garage. The presence of an inspection hole will greatly help the replacement event. Replacement can also be done using a jack. In most cases, the main muffler and resonator are dismantled; other parts rarely break.

To remove the main part, unscrew the fastening and connecting clamp. The module is disconnected from the resonator.
The resonator hangs on rubber hangers, lift it up and unfasten it.
We discard the sealing ring located between the nodes; when reassembling, a new gasket is used for connection.

The number of exhaust rubber bands on a Prior hatchback and sedan is different. The exhaust pipe on the Prior is attached to the exhaust pipe with a bolted connection, which is sometimes difficult to unscrew; it is advisable to pre-treat the bolts and nuts with WD-shkoy. Often after dismantling it is necessary to replace them with new ones. Before installation, it is recommended to clean all connecting elements from fumes and dirt. Removing the exhaust of priors “on the knee” is a tedious task, but doable!

high noise level;
exhaust gases entering the cabin;
increased fuel consumption;
reduction in engine power.

Exhaust pipe VAZ 1111 (Oka)

The Oka has a muffler separate from the exhaust pipe. There are 2 Oka models with VAZ engines, respectively, they are equipped with 2 types of mufflers and exhaust pipes:

Basic 1111 - a VAZ 1111 exhaust pipe is installed on it
Modified with engine 11113 - a VAZ 11113 exhaust pipe is installed on it

The differences between them are in the fastenings. In the first case, the pipe is secured with a clamp, in the second, a bolted connection is used.

The cost of a muffler for Lada Priora in Russia is from 1000 to 7500 rubles. The main task of a muffler is to reduce the noise of exhaust gases in the exhaust system to acceptable limits. It also reduces the toxicity of exhaust gases and their temperature.

The unit consists of a metal body (ideally stainless steel) and outlet tubes. The housing contains several channels and chambers through which flows of waste combustion products pass. As gas passes through internal structural elements, sound vibrations are suppressed. All units use a change in flow direction in channels located at different angles to dampen high-frequency noise.

Priora Muffler Dimensions

The exhaust system consists of several parts, each of which plays an important role. These include the exhaust pipe, catalyst, resonator and the muffler itself. The main functions it performs are noise reduction and reduction in the emission of harmful gases. Also, there is often a corrugation on the receiving pipe, designed to reduce vibration. A malfunction of any part of the exhaust system can affect the condition of the entire car and many other parts in particular, so it is necessary to regularly diagnose this element of the car.

System breakdowns

There can be many problems with the exhaust system. As a rule, repair is not possible; replacement of elements will be required. Let's take a closer look at them.

Rust and system destruction due to corrosion. Accumulating condensate especially contributes to this problem.
Inability to muffle noise. Typically, the malfunction is caused by the destruction of the internal partitions of the main muffler.
Breakage of fasteners. A characteristic symptom of the problem is a knocking sound from the muffler and the appearance of vibration.
Oxygen sensor malfunction.

The standard method for solving certain problems is to replace the element. In some cases, temporary solutions are possible, but if the muffler is “burnt out” or rusted, unfortunately, you simply cannot do without installing a new part.

The system for removing waste exhaust gases in a car is an important technical complex that performs many necessary functions: reduces toxicity in exhaust gases, reduces noise from vehicle operation, prevents the penetration of toxic products of fuel combustion into the passenger compartment of the car, participates in regulating the operational characteristics of the car, Thanks to the creation of the necessary resistance of exhaust gases, it creates a certain image of the car brand (timbre of sound, detail of appearance). On the Lada Priora, in this regard, replacing the resonator is not such a rare operation.

How to repair a muffler

If your car's muffler requires repair or complete replacement, it is not recommended to do this work yourself, since there is a high risk that you will only worsen the condition of the exhaust system, and possibly the entire vehicle as a whole. In order to prevent such a situation, contact only specialized car services. In our car service center, qualified specialists with the necessary competence in the field of working with exhaust systems will competently diagnose the exhaust system of your car, and, if necessary, repair or install a new muffler in the shortest possible time.

If you encounter any malfunction in the exhaust system and you need to diagnose it, repair it or replace the muffler, then our salon specialists will be happy to help you with this, since we carry out all types of this work!

Interestingly, the exhaust system in any car is one of the most important. Moreover, it includes many different nodes. And it is directly connected to the electronic control system (ECM).

These difficulties occur primarily due to increased requirements for the environmental friendliness of the car. “Priora” in this regard is quite a European option. The toxicity of its exhaust complies with the Euro-4 standard.

Mufflers VAZ 2108-2115 (Lada Samara)

Lada Samara can be roughly divided into 2 generations:

VAZ 2108-21099 – first generation
VAZ 2113-2115 – second generation

With the first generation everything is simple. The chisel in the hatchback body is equipped with a VAZ 2108, 2109 muffler, and in the sedan body there is a VAZ 21099 muffler.

In the second generation of Lada Samara, there is also a principle of division into 2 body types: hatchback - muffler VAZ 2113, 2114 and sedan - muffler VAZ 2115. But in each type there are 2 more subtypes: new

and old style

. I’ll say right away that in terms of interchangeability, they are absolutely the same.

In old-style mufflers, the exhaust pipe has an additional pipe bend; in new-style mufflers there is no such bend. Why was the extra bend removed? Perhaps in order to reduce the cost of production. Why it was there in the first place, unfortunately, is unknown to me.

As for the interchangeability of the first and second generation Lada Samara mufflers, both generations are completely identical in terms of fastenings. But if you buy a cheaper muffler from the first generation to install it on the second, you will have to bend the tail of the exhaust pipe. If you are going to do the opposite, then you are an extraordinary person, and on your car the muffler from the second generation will look ridiculously extraordinary.

Main components of the Priora exhaust system

As already mentioned, this is not one element, but several:

Timing (gas distribution system) exhaust valves.
Exhaust manifold with particulate filter (catalyst).
Oxygen sensor (Lambda probe) 2 pieces.
Middle part with resonator.
Tail section with muffler.

Each of these parts must be considered separately.

Release of gases in the cylinder head

This is part of the operation of the gas distribution mechanism. A full description of this mechanism is a separate issue of engine operation. It is enough to mention here that the 8 exhaust valves open in exhaust mode and the piston pushes the exhaust gases into the system. Namely, into the exhaust manifold.

Catalyst or particulate filter in the exhaust manifold

This is one of the most complex and expensive components of the entire exhaust gas system. Essentially, this is a device for afterburning unburned gasoline particles using catalysis. For this purpose, the thin walls of the longitudinal filter honeycombs are made of a special material. Contacting them, gasoline burns (figuratively). The output is ordinary water.

Set of Lambda probes for Euro-3 system

What is Euro 3 standard? In fact, this is the level of purification of car exhaust gases. It is according to the levels of vehicle access to Europe that these systems are distributed. There are several levels:

Euro level.
Euro 2 threshold.
Euro-3 (basic for Priora).
Euro-4 (Subsequent models and the latest “Priors”).
Euro-5.

Description of the exhaust system of Lada Priora, VAZ 2170, VAZ 2171, VAZ 2172

Lada Priora exhaust system: 1 – main muffler; 2 – suspension cushions of the main and additional mufflers; 3 – sealing ring; 4 – clamp; 5 – additional muffler; 6 – exhaust manifold gasket; 7 – exhaust manifold with neutralizer assembly (catalog collector); 8 – laying the exhaust pipe of the additional muffler

Exhaust gases are removed from the Lada Priora engine through the exhaust manifold 7, combined with the neutralizer (catcollector), an additional muffler 5 and the main muffler 1. There are two oxygen sensors installed on the catcollector 7: diagnostic and main (control). A metal-reinforced sealing gasket 6 is installed between the cylinder head and the exhaust manifold flange. The exhaust pipe of the additional muffler 5 is connected through a gasket 8 to the cathode manifold 7, and the exhaust pipe is connected to the flange of the main muffler 1 using a movable hinge. A toroidal metal-graphite ring 3 is installed between the flanges of the VAZ 2171 muffler pipes, forming a hinge, and the flanges have internal spherical surfaces. To reduce the transmission of vibrations from the power unit of the Lada Priora to the exhaust system and body, a vibration-compensating corrugated bellows in a metal braid is mounted in the exhaust pipe of the additional muffler. Catcollector 7 is secured with nuts on the studs of the cylinder head and is additionally secured to the engine with a bracket. The system elements are suspended from the body on four rubber cushions 2. To protect the engine and the base of the priora body from heating by the system elements, steel thermal screens are installed in front of the catalytic collector and above the additional muffler. In addition to them, an additional heat-insulating shield is installed in the engine compartment, which protects the VAZ 2170 steering mechanism from overheating.

Location of the exhaust gas system elements in the front part of the VAZ 2172 car: 1 – cathode collector; 2 – exhaust pipe of an additional muffler; 3 – bellows; 4 – front thermal shield of the additional muffler; 5 – additional muffler

Location of system elements on the vehicle.

Location of exhaust gas system elements in the rear of the vehicle: 1 – exhaust pipe of the additional muffler; 2 – movable hinge; 3 – main muffler

The Priora exhaust system does not require special maintenance. It is enough to periodically check the reliability of tightening of threaded connections and the integrity of the suspension cushions of the Lada Priora. In case of damage to system elements, through corrosion or burnout, they are replaced as an assembly, since the mufflers together with the pipes are non-separable units.

Warnings Before repairing the exhaust system, let it cool down, since during operation of the Lada Priora engine it heats up to a high temperature. Exhaust gases are poisonous and poisoning occurs unnoticed, so be sure to open the garage door before starting the engine!

To remove and install components of the Priora system, you will need: keys “10”, “13”, “17”, pliers with narrow jaws, a screwdriver with a flat blade.

Priora main muffler

This is an oval barrel, divided inside by special partitions. Connected to the resonator pipe and the exhaust pipe coming out from under the Priora at the rear. Thanks to internal baffles and inserts, the exhaust sound is practically smoothed out to a slight rumbling sound. Like the resonator, it is attached to the bottom using flexible suspensions.

Therefore, they are mounted on a special flexible suspension and have little freedom of movement both relative to the body and from each other.

What you need to prepare

You will need a fairly small set of tools, which, without a doubt, can be found in any garage. The list is as follows:

key to 13;
drill;
drill 1.5 mm;
Phillips screwdriver;
screws 2 pcs. (4 millimeters);
standard clamps for fastening the exhaust pipe;
2 muffler pillows;
mounting bracket.

When preparing a drawing, it is important to take into account the length of different types of bodies. If, for example, you assemble an exhaust according to the dimensions for a station wagon or sedan and install it on a hatchback, the pipes will protrude too far. The difference should be taken into account, and then the bumper and pipes will look more harmonious and elegant

The difference should be taken into account, and then the bumper and pipes will look more harmonious and elegant.

The main malfunctions of the Priora exhaust tract

Due to the fact that the operation of these components is associated with high temperatures, the most common breakdown is the burning out of some part. This could be the gasket under the manifold, or the wall of the muffler, catalyst or resonator. A separate part is the malfunction of the particulate filter or afterburner. But they are included in the section for repairing the injection part of the car, just like the Priora oxygen sensors. In other cases, it is either mechanical damage or simple rust.

The appearance of extra holes in the system is determined immediately and for sure. The engine exhaust just becomes loud and unpleasant. There is a crackling sound and sounds vaguely reminiscent of shooting. In this case, you need to go to the inspection hole, find the hole and replace the damaged unit. Relevant video on this topic:

What does the price depend on?

Installation of wiring, amplifier for audio system in Lada Priora

To manufacture the body and tubes of high-quality components, special stainless and heat-resistant steels are used, designed to operate under constant thermal load with sudden temperature changes. These mufflers last longer, but they are the most expensive. Spare parts made of aluminized steel or aluminum-zinc will also last a long time. To reduce the cost, “ferrous” alloys are sometimes used.

The larger the muffler volume, the better. Other factors that increase the service life and increase the cost of the unit are thicker walls and complex internal design, as well as additional thermal protection.

Resonator

Which muffler to choose

Stainless steel or aluminized steel

Mufflers for cars of the Priora family are made of steel of various thicknesses. The thicker the steel, the stronger the muffler. The type of steel is no less important. Most car enthusiasts prefer stainless steel that has been proven over the years. However, modern aluminized steel is not inferior to it in terms of resistance to corrosion, and is significantly superior in overall strength and ability to absorb vibrations. This means that an aluminized steel muffler will be quieter than a similar one made from stainless steel.

Manufacturers and prices

Exhaust system parts for Lada-Priora cars are produced not only in Russia. There are mufflers and resonators made in Poland, Turkey and Germany.

A muffler for a Priora costs from one to five thousand rubles. At the lower end of the price range are models made of thin steel; aluminized models usually cost at least three thousand rubles. The situation is similar with resonators. Prices for them start at about one and a half thousand rubles.

Possible inconveniences associated with a quiet muffler

It is also necessary to test in action how the exhaust system works so that gases exit normally through the exhaust pipe. Therefore, it is necessary to check at higher speeds, then it will be possible to draw the right conclusions. But as a rule, gases will escape through such a resonator without difficulty.

And then in the video there is another way to reduce the sound of the muffler, making a really very quiet exhaust system:

Ways to muffle the exhaust sound

Before tuning the exhaust system, you need to understand the reasons why the sound of the engine becomes louder over time. The operation of the engine itself is a fairly loud process, but the muffler and other components of the exhaust system perfectly suppress this loud noise. Without a muffler, the engine noise is very loud.

The explosion releases energy that pushes the piston, and when the piston has moved the required distance, the exhaust valve opens, through which the exhaust gases exit and go further through the exhaust system. To effectively absorb noise, thick metal parts are used. So, the thicker the metal used in the exhaust system, the quieter the car will drive due to the fact that there will be less vibration.

The exhaust manifold is the first one to absorb the noise, which is why it is made so large and thick, so it best dampens the noise that comes from the cylinder block. Even if you compare the exhaust pipe of any more or less normal foreign car with the exhaust pipe of a domestic car, you can see that in foreign cars the pipe is heavier and thicker, which is why such a car runs quieter.

This is why when you drive an old VAZ 2114, the noise is such that you can’t hear what the passengers in the rear seats are saying, which is why you start thinking about how to muffle the exhaust sound.

The exhaust system also has a resonator, which is needed to reduce the speed of gases through the exhaust pipe. And after the resonator comes a muffler. When exhaust gases pass through the resonator, they lose some energy and continue to flow more slowly.

Gases lose the largest share of their energy in the muffler. If we consider a good muffler, then it contains several separate housings, after passing through which little remains of the noise.

Workflow Stages

Types of Dual Homemade Silencers

Let's consider the simplest and low-budget method of installing a dual exhaust on a Lada Priora with the installation of outlets from the muffler pipe under the rear beam of the car. Note that here you can choose one of two options:

Distribution of pipes of different lengths with welding of branches to the main muffler.

This is interesting: Nissan Safety Shield

Two pipes of different lengths are welded to the main muffler pipe

Welding two pipes with similar lengths, angles and number of turns to the main muffler pipe.

Two identical pipes are welded to the muffler pipe. Remember that different lengths of pipes, although they affect the amount of gases released (this will be especially noticeable at high engine speeds), do not affect the operation of the engine itself.

Preparing for work: tools and materials

To carry out a full cycle of work, we will need to prepare a set of simple tools and a number of inexpensive materials:

wrench (socket, open-end, socket) to “13”;
electric drill with 1.5 mm drill;
Phillips screwdriver;
self-tapping screw 4 mm - 2 pcs.;
standard exhaust system fasteners (clamp + ring);
muffler cushion - 2 pcs.;
fastening bracket (holder - bracket).

A clamp with an O-ring, a homemade bracket, a muffler cushion.
At the preparatory stage of work, you need to take the necessary measurements and draw up a simple diagram of the design of a double exhaust. There is simply no universal drawing that would be suitable for each individual project. Professional craftsmen advise taking all measurements at the place of work, transferring the data onto paper in a form convenient for you.

Diagram of a homemade dual exhaust outlet bracket

Note that the exhaust system of the Lada Priora sedan and station wagon differs from the same equipment installed on hatchback cars in the length of the main muffler pipe. Installing a dual exhaust on a car with such a body for the first two modifications will result in the system pipes protruding from under the bumper by 150–160 mm.

How to make it yourself

Let's look at the process of installing a bifurcated muffler using the example of a finished sample - all the steps we performed are suitable for installing any structure of this type. The only nuance that can affect the progress of work will be the possible deviation of the pipes of the independently manufactured system from the fastening elements of the original muffler. However, this is not a problem, since all brackets can be easily made and installed with your own hands.

We install the car on a lift or inspection hole, prepare all the necessary tools, be patient and get to work:

We dismantle the original main muffler by disconnecting the clamp at the point of its attachment to the resonator (additional muffler).
We will hang the right part of the new structure on its seat, installing it on the existing cushions (replacing them in case of critical wear). We do not attach the left side of the muffler yet, but only connect the common terminal of the dual exhaust to the resonator, slightly “baiting” the clamp and the O-ring.

Installing a part of the structure on the seat of the original muffler.
Let's attach the left bend to the side member on the bottom of the car, mark the attachment point of the bracket-bracket.

Left part of the structure, mounting bracket and muffler cushion

Using a drill, drill two holes and securely fasten the bracket with self-tapping screws.

Preparing holes for installing the bracket-holder

We hang the muffler outlet on the bracket using a fastening rod, after inserting the cushion into the holder bracket.

Installing an additional muffler outlet

In our case, the elements of the dual exhaust need to be connected to each other using a clamp with O-rings (do not tighten too much). We exclude this stage of work when installing a solid structure.
