What you need to replace the muffler corrugation of a Lada Vesta with your own hands

If the driver does not want to repair the car himself, then it is better to seek help from a car service center. Craftsmen charge on average about 1,600 rubles for work.

But more often, drivers change the corrugation themselves. To do this you will need:

• inverter with electrodes;
• a set of keys;
• reciprocating saw (some people use a grinder, but when using it there are more sparks and there is a risk of hitting the body).

The elastic element must be removed at the inspection hole.

Replacing the Vesta muffler corrugation: eliminating the defect in a car service center

If “symptoms” of problems occur, you should immediately contact a car service for a replacement, which is as follows.

A grinder is used to cut out the failed corrugation. An additional muffler is removed along with it - this part is not reliable and may fail immediately after repair.

It is replaced with an alternative one together with the replacement of the flexible coupling, so as not to have to come for repairs in the near future. An elongated elastic coupling is installed; it works better and is more durable.

They are scalded on both sides and an additional muffler is installed.

At first glance, this work is not difficult, but it must be done very carefully. Any, even the slightest, distortions will lead to its rapid failure.

The corrugation on the vest burns out. what to do

Changing the corrugation every 10,000 km is not an option. On foreign cars, even the most budget ones, the corrugation works up to 100-120 thousand without problems. Ask the owners of Fords, Chevrolets and Nissans.

The reason lies in three factors:

1. Unbalanced engine mounting on supports. Because of this, the slightest vibration of the motor leads to rapid wear of the corrugation. In addition, gear shifting becomes difficult, which also depends on the quality of engine vibration insulation.
2. The quality and configuration of the corrugation on the Lada Vesta does not quite correspond to the parameters of the engine and gearbox. As a result, critical wear of the exhaust system element occurs much earlier than the nominal period.
3. Incorrect installation of the new corrugation. If an exhaust system technician starts welding a new, best-in-the-world corrugation onto a hanging muffler, this will not lead to anything good. To replace the corrugation, the muffler must be removed.

Much has already been said about the inconsistency of the rear (lower) engine mount, which is attached on one side to the subframe and on the other to the gearbox housing. And many options were found for replacing the original support with another. We talked in detail about replacing the lower support, with catalog numbers and prices here.

And yet, there is a less radical, but no less effective method of tuning the rear mount of a Vesta engine than buying an expensive and not particularly affordable rear mount from Vesta Sport. (Their retail release was stopped a year and a half ago).

Vehicle manufacturer's warranty

Drivers' interest in the Lada Vesta has increased not only demand, but also the number of complaints about malfunctions. First of all, many complained about the appearance of signs of exhaust system failure.

AvtoVAZ noted that such a defect appeared due to the design features of the car. Symptoms of a malfunction arise due to contact of exhaust system elements with the surface of the body.

The factory advised that if such signs appear, contact the dealers directly. Centers do not have the right to refuse to carry out repair and diagnostic work.

AvtoVAZ gives a guarantee on corrugation for a year. Repair work is free.

Replacement algorithm

• Remove the battery terminal;
• Disassemble the exhaust system down to the pipe bend;
• Using a grinder, cut out the part. The cut must be smooth to ensure high quality welding of the product. The part is cut closer to the edges. After cutting the part, carefully clean the edges, remove traces of erosion and dirt;
• Remove the lambda probe;
• Fix the pipe and secure it by welding in several places to prevent the part from turning over during final fixation;
• Dismantle the pipe;
• Weld the new product;
• Put the structure back in place and secure it;
• When replacing a spare part, replace all gaskets in the exhaust system.

Modification or replacement of the rear support of the vest

The rear engine mount on the Lada Vesta consists of a housing and two silent blocks, small and large. If the bushing in a small silent block is pressed in tightly enough and does not move under the influence of axial loads, then in a large standard silent block everything is different.

The rubber part of the large silent block is simply inserted into the body and has absolutely no fixation. Therefore, the support allows the engine to have a much larger vibration amplitude, which leads to rupture and burnout of the corrugation, as well as unclear gear shifts.

How to get rid of the hum in the muffler of Lada vesta?

Many Lada Vesta owners complain about noise from the muffler while traveling.
The hum, squeaking and rumbling are especially pronounced at 3000 engine speeds and when the gas is released. And sometimes the noise is noticeable even at idle. The problem is explained by the unsuccessful design of the factory corrugation. It does not dampen vibration effectively enough.

If the car is under warranty and is subject to a service promotion, then the official dealer will fix the fault free of charge. You just have to wait for the delivery of spare parts and replace the middle part of the muffler. But this will not solve the problem for long. Over time, the corrugation will begin to resonate again and the unpleasant noise will return. The hum is not explained by a factory defect, but by the unsuccessful design of the standard muffler. Therefore, replacing the part with the same one will not bring the desired result.

There are two ways to get rid of the hum for a long time. Rebuild the corrugation into an extended one or replace the entire muffler.

The Bosal muffler corrugation 45x200 mm fits perfectly on Vesta. Due to its elongated shape, it better dampens vibration and noise.

Replacing corrugations (overcooking) takes our craftsmen about an hour and a half. As a result, noise and hum disappear, and driving the car becomes much more comfortable.

On a car with a mileage of more than 100 thousand km, we advise not to overcook the corrugation, but to change the entire muffler. We recommend CBD mufflers for Lada Vesta. For cars produced before 2022, there is a medium CBD muffler for Lada Vesta (1.6 and 1.8) from 2021-2021. For cars after 2021 release - a medium CBD muffler for Lada Vesta (1.6 and 1.8) from 2022.

Replacing the middle section of the muffler takes approximately 30 minutes.

You can change the muffler yourself. On our YouTube channel you can watch a video in which a master installs a new spare part. The problem can only arise with soured nuts. Often they cannot be unscrewed without an air gun.

Some car owners try to fix the corrugation braid with clamps or springs. Then it begins to vibrate less and the noise subsides for a while. According to the experience of our masters, this is an ineffective and unreliable method. The hum remains the same or dies down slightly while the clamps firmly fix the braid. But after a couple of trips the clamps loosen and the noise returns.

How to change the corrugation on a Vesta

The corrugation on the Lada Vesta requires replacement in case of any type of breakdown. The part cannot be repaired. You can carry out restoration work with your own hands, but it will only give a temporary effect. They are suitable if it is not possible to change the part in the next week.

To restore the driver will need a bandage and epoxy resin. The car needs to be driven into the inspection hole, soaked in a bandage with epoxy and wrapped around the corrugation. However, this measure is temporary. It is not recommended to drive with such corrugation.

Which corrugation to put on the “vesta”

“Lada Vesta”, “Cross” and “Sport” are equipped with 1.6 and 1.8 liter petrol engines. Previously, it was recommended to install double-layer corrugations on cars with such power plants. However, now in the manufacture of parts they use 3 layers of metal braid.

Interlock's inner layer is made in the form of a metal hose.

Innerbraid elastics are slightly less expensive than Interlock. The inner layer is a regular metal braid. The service life of these parts is shorter. The reason is a higher burnout rate. A solid metal sleeve can withstand higher temperatures than steel threads.

The difference in price is 50-100 rubles, so it is better to buy parts of the first type. Such corrugations are more common in Russian car dealerships.

AvtoVAZ's response to corrugation and muffler

Questions to AVTOVAZ regarding the problem in the operation of the Vesta exhaust system were asked live on “Ladnaya Mechanica”:

Question: On Vesta, the exhaust system growls in 1st, 2nd, 3rd gears around 2000 rpm, as if the corrugation is not working and dampening vibrations.

Answer: Perhaps this problem is individual. Perhaps there is a contact somewhere on the body causing a hum. Show your vehicle to a warranty engineer.

Question: Everyone's exhaust howls around 3000 rpm. Most people digest corrugations.

Answer: If you have a specific problem with a specific vehicle, please contact your dealer. If the problem cannot be solved, the presenter suggested writing about it in a PM, indicating the VIN of the car and the dealer where you are being serviced.

Some owners of the Lada Vesta sedan during the operation of the car notice extraneous sounds similar to rattling, rumbling or humming of the muffler. According to reviews, noise is noticeable not only at idle, but also at speeds of 110-125 km/h (at 3000 rpm and when releasing the gas). Let's figure out what the cause of this problem is and what answer AvtoVAZ gives.

Signs of failure of the Lada vesta muffler corrugation

An increase in the sound of the motor and a change in its tone are the first signs of failure of the elastic element. The driver hears a characteristic growl. It appears both while driving and at idle.

The noise increases at speeds of 90-110 km/h. In this case, the engine speed reaches 3 thousand per minute.

Replacing the Lada Vesta corrugation is also required if an exhaust smell occurs. Exhaust gases enter the vehicle interior, causing poisoning for the driver and passengers.

Deformation of the elastic element is also indicated by a decrease in motor power. However, this sign is not typical. A decrease in power indicators is also possible due to other breakdowns.

AvtoVAZ advice in practice

1. On the advice of AvtoVAZ, one of the owners of the Lada Vesta sedan turned to the LADA dealer with the problem of “glushak humming.” After the diagnosis, the necessary parts were ordered, but we had to wait 10-14 days. As a result, the exhaust system was repaired under warranty (the vibration damping clutch and additional muffler were replaced). The problem was solved. The owner talks about the problem in two videos:

2. However, after a month the muffler noise returned. This time the owner did not contact the LADA dealer, but decided to replace the corrugation and resonator himself at a third-party service station. During the conversation with the service workers, it turned out that several owners of the Lada Vesta sedan had already contacted them at the service station with a problem with the muffler hum.

How to solve the problem

:

• We replaced the standard vibration damping corrugation with an extended one.
• We replaced the standard additional muffler with an alternative one (according to the service station workers, the factory one rattles like a tin can).

The work was carried out using welding. The whole process on video:

Attention!

This information is posted for informational purposes and is not an advertisement for the service in the video. You can replace the vibration damping corrugation or muffler at any service station, including an official dealer. In addition, there is a budget-friendly way to modify the design and solve the hum problem.

Have you encountered rattling noise in the muffler on Vesta? Did you manage to solve the problem? Leave your feedback in the comments.

By the way, do not forget to check the muffler mounts. During the life tests of Vesta, over 100 thousand kilometers (this is equivalent to 5 years of operation), all muffler suspension cushions (gingerbread) were changed 2 times. Another cause of rattling may be an additional muffler (resonator).

The Lada Vesta exhaust system consists of several components. The muffler corrugation is one of the main ones. Replacing the muffler corrugation of a Lada Vesta is a specific job in which you cannot do without a welding machine. The muffler corrugation of a Vesta car operates under high voltage and extreme loads. The muffler pipe is designed to absorb engine noise and vibration when driving.

Car owners note the appearance of uncharacteristic sounds when driving in the exhaust pipe area. Drivers hear rattling, buzzing, and creaking noises. The sound appears when the engine is idling and when driving. The sound becomes especially obvious when driving at a speed of 90-110 km/h and when the engine speed reaches 3000 per minute. By the way, problems also occur with the resonator. The cause of this phenomenon may be corrugation. The Vesta corrugation is made of high quality steel, has a small size (more on that below), and huge loads lead to its breakage. In some cases, it may be necessary to replace the corrugation on the Lada Vesta, and in some cases, it is enough to modify it, the price for it is not so small - read the article to the end and you will understand what we mean!

Application of springs

In this case, to independently eliminate the noise from the Vesta muffler, you need a little more materials:

— 2 springs from classic brakes (drum);

- nuts;

- clamps.

It is necessary to install clamps in front and behind the muffler and secure them. And after that, tighten the springs between them - one on each side. These springs will tighten the corrugation.

But opinions regarding this modification vary. Some sedan owners claim that both methods work and indeed, if not completely eliminate the unpleasant sound, then, in any case, significantly reduce noise.

Reasons for failure

The corrugation breaks more often than other parts of the exhaust system. The reasons for the breakdown are as follows:

• Mechanical deformation. Due to the location of the corrugation, it is open to impacts when driving over bumps and uneven surfaces. Any bump in the road can catch the braid and tear it. Repair in this case is impossible.
• Wear of engine shock-absorbing mounts. Worn shock-absorbing cushions do not provide proper support for the engine. This affects the operation of the entire exhaust system of the car. The tensile load increases, which can damage the braid of the elastic element.
• Poor quality fuel. This can also lead to rapid wear of the part. Drivers should also not add any additives to the fuel that are not recommended by the car manufacturer.
• Reagents. Have a negative effect on the part. The chemicals not only prevent the formation of ice on the road, but also corrode the steel. The connections have a negative effect on the body iron, muffler corrugation and other parts of the car.
• Damaged muffler fasteners.
• The load on the elastic element increases, which can lead to its complete rupture.
• Natural wear and aging of corrugation.

In each specific case, a breakdown should be diagnosed in order to understand its cause.

Dealer work

As it turned out, one of the owners of the sedan, who encountered noise from the Lada Vesta muffler, heeded the advice of the presenter and went to the dealership. There, diagnostics were carried out, after which the warranty engineer placed an order for all the necessary components. They had to wait from 10 days to 2 weeks.

When the spare parts arrived, the exhaust was repaired under warranty, including the replacement of the muffler (optional) and vibration damping coupling. This solved the noise problem of Vesta's jammer.

In the video, the owner of this sedan spoke about the situation

What does a car enthusiast need to know when it is necessary to replace the muffler corrugation of a Lada Vesta?

Owners of Lada Vesta must regularly undergo vehicle maintenance at certified car repair shops. They will inspect the entire vehicle, check the performance of the exhaust system, and determine the condition of the engine shock absorbers and muffler mountings.

In our service, trained specialists will identify the failed unit and carry out repair work. During which we use high-quality spare parts from trusted suppliers.

After each operation is completed, a quality engineer inspects and accepts the work. The owner of a Lada Vesta receives a warranty for services provided or installation of components.

They also receive a warranty on installed spare parts. Car enthusiasts who have had their cars serviced become regular customers of our car service center.

They get the opportunity to have their car serviced out of turn and receive benefits or discounts on their next visit to the service center to pay for our services.

DIY repair

However, the joy did not last very long, since a month later the noise from the Vesta muffler reappeared. Seeing the current situation, the owner of the car decided not to contact the dealership again, but to fix the problem at another service station. After talking with one of the service employees, it became clear that they regularly receive requests for repairs to the Vesta muffler.

To fix the problem, 2 operations were performed:

1. Replacing the factory corrugation (vibration dampening) with an extended one.
2. Removing the factory additional muffler and replacing it with another one. According to station employees, the standard muffler rattles a lot.

For example, Bosal corrugation with parameters 45×200 mm, which can be found under article number 265-309, is a good fit.

All works are demonstrated in the video.

A similar replacement can be carried out at any other service station or directly at the dealership.

Problem solving

Contact an authorized dealer. When contacting a service center, the vehicle will be subject to a diagnostic examination and the cause of the symptoms will be identified. If it is necessary to replace parts, specialists place an order for a new car muffler element. You will have to wait 1.5-2 weeks. After this, a replacement is made.

Replace the part yourself

Doing the work yourself requires ordering a new part. Car owners replace the standard component with an extended one. Many people, along with the corrugation, replace the standard exhaust pipe and muffler, which rattles too much. Sometimes car owners carry out modifications. This option is suitable for those who do not have the opportunity to install a new part, and have difficulties when contacting an official dealer. Refinement will not require money, physical resources or time.
