In detail: do-it-yourself muffler repair on a VAZ 21099 from a real master for the site my.housecope.com.

We will show you how to do it yourself repair and welding of a muffler in VAZ 2109 21099 2108 cars with your own hands. In principle, a muffler does not cost so much money to repair it, but for someone this instruction will be useful and will save money. Before starting welding, thoroughly clean all surfaces with a grinder and a special nozzle. Assess the general condition of the muffler, it is possible that it makes no sense to repair it and it is easier to buy a new one. In our case, this is the second muffler repair.

It is not difficult to repair a muffler in this way, if you have a welding machine available, all welding operations are elementary and do not require special skills.

The muffler from the VAZ 21099 is replaced if there is a loud roar. In this case, you will have to replace the failed corrugation or the entire main part as a whole.

The process of replacing the muffler has some nuances. Initially, auto mechanics recommend making the right choice of this unit. Its main task is to provide resistance to counterpressure. A muffler is required to reduce noise from gases emitted into the atmosphere.

A muffler of the following type can be installed on a VAZ 21099:

Dissipative. This device has a simple design and is effective at attenuating noise waves. Of the minuses of such a unit, auto mechanics distinguish the lack of environmental friendliness.
Reactive. The principle of operation of this device is the addition and mutual elimination of sound waves.
Combined. The direct-flow unit minimizes the loss of power, and the labyrinth unit improves sound damping.

It should be noted that any muffler provides a comfortable and quiet ride, including the elimination of a large amount of harmful exhaust gases. The muffler from the VAZ 21099 is replaced only by a similar unit of the corresponding model. Often, a certain part of it fails. It should be borne in mind that mechanical damage is eliminated on the muffler using gas welding 1-3 times.

Experts refer to the reasons for dismantling the old and installing a new unit of this type:

constant heating or cooling;
regular heating to a significant temperature;
corrosion on the muffler metal;
mechanical damage associated with the close location of the unit being replaced to the road surface;
the negative effect of particles from the roadway;
vibration and so on.

Signs by which a motorist can understand that a muffler needs to be replaced:

air is sucked into the cylinders;

a peculiar sound is heard from under the hood;

exhaust gases erupt under the hood.

Before proceeding with the replacement of the muffler, you will need to select one of the above types of this unit. Often, VAZ 21099 car owners buy a tuned model.In some cases, the gasket is replaced. To do this, you need to lift the car into the inspection pit. Then the air filter is dismantled and the battery is removed. After unscrewing the air intake nuts, this unit is removed. When removing the fastening nut, you will need to replace the additional muffler with a VAZ. Initially, the condition of the old unit is checked.Next, you need to unscrew the "weight" nut, remove the wire from the hairpin. Then dismantle the nuts that secure the inlet pipe of the cooling system. Replace the seal gasket and unscrew the nuts securing the exhaust manifold.Then disconnect the last manifold and remove the corresponding gasket.The final stage of replacing the muffler involves the installation of dismantled elements. This takes into account the reverse sequence and the charging of the cooling system.Positioning the unit on the machineAs for dismantling the old and installing a new muffler on the VAZ 21099, this process is carried out in a similar way. It is recommended to replace the rubber bands at the same time.The middle muffler element is replaced as follows:

Remove the middle part that is burnt out. If necessary, a grinder is used.

Install a new item.

Carry out welding work.

When repairing or replacing a muffler from a VAZ 21099, auto mechanics recommend that drivers pay special attention to the fasteners. These bolts are often impossible to remove with your own hands. In these cases, soaking and leverage is not an effective technique. Cutting bolts with a grinder is considered a more universal method. Then they are removed and new bolts are installed in their place. Image - Do-it-yourself muffler repair on a VAZ 21099

The exhaust system is considered to be one of the leading systems of the current vehicle. Timely replacement of the muffler for the VAZ 2108, VAZ 2109 and VAZ 21099 plays an important role in the operation of the car. Not only the correct emission of carcinogenic substances into the planet's atmosphere depends on it, but also a decrease in the noise level of a working car. In addition, when tuning a vehicle, a stylish "glushak" is an indispensable element of the VAZ 2109 exterior.

In the event of a defect in this element of the exhaust system, the motorist has two scenarios for the development of events. These include:

replacement of the VAZ 2109 muffler;
repair of an old product - corrugations of a muffler, a catalyst, or simply replacing gaskets.

If everything is clear with the first, that is, we act according to the scheme: went - chose - bought - installed, then the repair of the VAZ muffler requires the concept of its necessity. If the defect consists in burning out the walls of the muffler, then repairing it is useless and even patches applied by the welder will not give the long-awaited effect. After a short time, next to the "patch" applied by the welder, the car enthusiast will have a new breakthrough site for exhaust gases.

It's another matter if the defect lies in the burnout of the muffler pipe in the resonator region. This happens, here the walls of the product are strong enough, and if a small affected area is detected, the "patch" applied by the welder can lead to a positive result, and the product can be in operation for a long time.

Replacing the muffler VAZ 2109 with your own hands

We return to another scenario, when a decision is made to replace the product. replacement of the muffler VAZ 2109 with your own hands is absolutely real, even if the motorist does not have confident skills in plumbing.

In this situation, an important point is the purchase of a new spare part in a car dealership. This product is not one of the scarce goods, but the car enthusiast can unknowingly sacrifice quality for the sake of a beautiful exterior of the product. Based on personal experience, we recommend purchasing the so-called. "Regular" or original parts, especially since their price is quite affordable. You should not buy beautifully decorated parts, because the quality of the product is always brought to the slaughter of beauty, the same lightweight part indicates a violation of the technology of its manufacture: either it is empty, or the material of manufacture is used with the wrong characteristics.

Having chosen the necessary part, we start preparing for its installation on the car

At this stage, you need to choose a place where to replace the muffler (overpass or pit for repairing the car's suspension), turn on 1st gear and install the car with the rear wheelset fixed.

For the production of work, it is necessary to prepare:

muffler for replacement;
WD40 solution to facilitate removal of fasteners;
wrenches for "13" - 2;
wrench for keys.

The sequence for dismantling the muffler on the VAZ 2108 - 2109:

The clamp with fasteners is dismantled, securing the connection of the product with the resonator;
We make the separation of the elements of the exhaust system with the removal of the seal ring;
Unfastened rubber hangers that hold the product in a given position. To do this, you need to press the product against the bottom of the car;
The stern cut of the "glushak" is placed on the surface and dismantled from under the vehicle;
The steps for installing a new product are carried out in the reverse order.

Important: When replacing a muffler with a VAZ 2109, the rings - seals should also be supplied unused to exclude obturation of exhaust gases and better tightness in the "resonator - muffler" assembly.

Withdrawal: 1) First, remove the O-ring and the clamp that holds the resonator together and the rear of the muffler by unscrewing the two clamp fastening nuts. (How to remove the fastening clamp, you will find in the article: "Replacing the resonator", point "1-2")

2) Then remove the three suspension pillows from the muffler, for this:

• First, pry off with a screwdriver, disconnect the front suspension cushion from the bracket at the rear of the muffler.

• Further, without removing the screwdriver from your hands, in the same way detach the rear suspension cushion from the bracket.

• Finally, disconnect the side cushion from the left side of the rear muffler.

Note! Replace all torn, as well as lost their elasticity, hanging pillows with new ones!

3) After removing the pillows, remove the rear muffler from the vehicle.

Installation: 1) First install the new rear muffler on the front suspension cushion.

2) Then onto the side hanging cushion.

3) And at the end of the operation, install the muffler on the rear suspension cushion.

4) After finishing the suspension of the muffler, connect the rear part of the muffler with the resonator by inserting an O-ring between them, and over the ring, installing a fastening clamp. (For more details, see the article: "Replacing the resonator", paragraph "2-3")

The middle muffler element is replaced as follows:

The exhaust system does not have a complex structure and structure at all. Its main task is to release waste gases. But not everything is so simple. If exhaust gases escaped into the atmosphere, the damage to nature would be enormous.Therefore, modern developments were applied that allow gas to be purified before exiting, making them safer for the environment.Let's study the exhaust system using the example of the VAZ 2109 model.The exhaust system of all domestic cars is approximately the same. This greatly simplifies the issue of self-repair without the involvement of specialists.The exhaust system (BC) includes several main components.System elementA special probe is placed inside this pipe. This device studies the composition of exhaust gases, monitors and analyzes the composition of the mixture that goes to the cylinder blockThis is the very element of the system that allows you to minimize the harmfulness of gases escaping from the aircraft.It is mounted to the catalytic converter with a special clamp. The task of the additional muffler is to receive the main noise, therefore, the sound at the exit from the pipe is insignificantThe same component that peeks out from under the rear bumper of your car. It connects to the additional muffler with a collar Image - Do-it-yourself muffler repair on a VAZ 21099

Main components and fasteners

The entire exhaust system of a VAZ 2109 car is in a suspended state and is held by the presence of fastening rubber suspensions. The hangers, in turn, are bolted to the bottom of the machine.

The exhaust system itself, together with the muffler, is quite reliable and durable due to its simple design.

Frankly speaking, there is nothing to break down when you compare the aircraft with the engine, fuel, oil system, and so on.

The most common and unpleasant situation that can happen to an aircraft on a VAZ 2109 is a punctured muffler. This is due to the quality of our roads, or rather to their absence.

Often traveling along our "magnificent" roads, you now and then run into all kinds of bumps, potholes, holes. If, after passing another similar obstacle, the car began to make a noticeable noise, which was not the case before, then the most likely outcome is a hole in the main muffler. The presence of the hole does not allow working calmly, quietly and efficiently as before.

The law of the Russian Federation states that it is prohibited to operate a car with a broken muffler. Therefore, the only correct solution would be to repair the unit.

There are two ways to repair the main muffler:

Replace with a new one. Practical, easy and fast. You can do this work with your own hands without any problems.
Weld the hole. This option is suitable only if the hole can be welded at its size, and you also have experience in welding. It is better to entrust welding to professionals.

To remove the muffler, follow a fairly simple step-by-step instructions.

Equip yourself with a 13 deep socket head, a 13 spanner wrench and a ratchet.

Drive the car into the inspection pit, or lift it with a lift. You probably don't have a lift in your garage, though. But almost all garages in auto cooperatives are equipped with holes.

Wait until the entire exhaust system has completely cooled down, otherwise burns cannot be avoided.

Disconnect the main muffler from the resonator, i.e. the additional muffler. To do this, find the clamping strap. The fastening nut is gripped with a spanner to prevent it from turning. At the same time, the bolt is unscrewed with a ratchet.

After unscrewing the bolt, remove the fasteners, disconnect the elements of the exhaust system, remove the clamp and free the main muffler from the resonator.

Carefully remove the front end of the muffler from the rubberized suspension.

Remove it from the rear suspensions and pull the damaged element out.

Then proceed as appropriate. As we noted, a punctured muffler can be welded on, or a new one can be installed in its place.

Reassembly is carried out according to the specified instructions, only in the opposite sequence.

The catalyst heats up to 600 degrees Celsius when the engine is running, so it takes longer to cool down than a couple of mufflers. Make sure the element has cooled down before starting work.

To dismantle and replace devices, you need:

Disconnect additional muffler from catalytic converter. To do this, the nuts are held with a spanner wrench, and the fastening bolts are unscrewed with the second tool;
In a similar way, the bolts connecting the catalyst and the intake pipe are unscrewed from their places;
Next, the catalyst is carefully removed from the rubber suspensions;
We take a new catalyst, install it in the reverse order.

The exhaust system provided for the VAZ 2109 model is outrageously simple. This pleases the owners pleasantly, since they do not need to spend a lot of effort, time and money on repairs. Most of the work is done independently.

The muffler is extended along the entire length of the car body and is led out from under the rear to get rid of exhaust gases. The main task of any muffler is considered to be the reduction of the noise level and the conversion of sound waves into heat waves. That is, without an exhaust system, a car cannot work in principle. With mufflers for VAZ 2108/2109 cars, the situation is rather complicated: we can say that the exhaust pipe is the most "sore point" of these models. Therefore, the owner must prepare in advance for the fact that sooner or later he will have to deal with glushak malfunctions and independently replace this part of the car.Today car dealerships offer a large selection of original and tuned mufflers for VAZ 2108 and VAZ 2109 cars. Structurally, they are all similar, the only difference is the service life.Original high quality mufflers are manufactured at AvtoVAZ itself. At the same time, both aluminum and stainless steel are used in the manufacture, due to which the walls of the case do not burn out for a long time. Self-made mechanisms and forgeries quickly fail, since the wall thickness of the resonator must be at least 2 mm.The entire exhaust system of the VAZ 2108/2109 consists of three elements:additional muffler (or resonator);All three elements are interconnected by pipe ends that fit perfectly into each other and completely seal the interior space. For reliable fixation, reinforced gaskets are also used. The pipe is attached to the engine exhaust manifold using a flat flange and four studs.The rear part of the device (directly the exhaust pipe) is fixed to the bottom by five rubber hangers. It is made up of two pipes, the first is connected to the flange at the collector, the second to the gas receiver.A resonator (or an additional muffler) is a barrel with baffles inside and a tube with holes. Passing through the holes, sounds and noises enter the resonator chambers and are quickly converted into thermal energy.In terms of its structure, the main "glushak" is similar to the design of the resonator. It is also assembled by the rolling method, that is, without the use of a welding machine. This technique avoids corrosion. Image - Do-it-yourself muffler repair on a VAZ 21099

1-flange, 2-armored gasket, 3-bracket, 4-main muffler, 5 and 7-suspension rubber bands, 6-resonator, 8-brackets, 9-catalyst, 10-insert, 11 and 12 - attachments to the manifold

That is, the exhaust gas removal system on the VAZ 2108/2109 is arranged in the same way as on the previous VAZ models. The only difference is in the "nine" mufflers - a catalytic converter is installed there (on injection versions). The task of the catalyst is to reduce the toxicity of emissions into the environment and increase the efficiency of the engine due to the low resistance of the exhaust.

You can identify faults in the operation of the muffler yourself, and without having special knowledge in the automotive industry. First of all, sometimes observe the composition of the exhaust gases while driving. If, when you press the gas pedal, black smoke escapes from the pipe, then the mechanism is probably burned out and has holes.

Experienced car enthusiasts know that it is better not to bring the state of their "glushak" to a critical one, but to identify the smallest malfunctions in advance:

Check for knocks and gurgles in the exhaust pipe while driving.

Jack up the car, inspect the exhaust pipe. All parts must be free of rust, burnout or holes.

Watch for moisture dripping from the joints of the pipes of the muffler. The accumulation of condensation will quickly lead to the formation of rust and corrosion of the metal.

Evaluate how hot the engine gets after short trips. If the engine is seriously overheating, then this may serve as the first signal that the exhaust system is not working correctly.

Most often, motorists complain that the device begins to knock hard while driving. In this case, the blows of the pipe can be made either against the body of the gas tank, or against the body of the car.

The knocks can be very loud, which leads not only to a decrease in ride comfort, but also to a rapid deformation of the muffler itself. In these cases, it is necessary to immediately take measures to isolate the pipe from the tank or body:

change hanging rubber bands (it is quite possible that during operation they are very stretched and can no longer hold the pipe in one place);

if the knocking started after replacing the device, then it is necessary to turn the mounting flange and make sure that all the gaskets are in their places evenly;

if the muffler was replaced by a "cooperative", home-made or from another car model, then you need to try to ensure that all fasteners and joints exactly match the original.

In case of strong swinging of the pipe, it is necessary to replace the rubber bands with new ones.

If none of these measures work, you will have to use a thick piece of rubber to pave the impact of the muffler. The rubber will eliminate the sound of impacts and keep the pipe surface from deforming.

It is very easy to pierce the device - just drive at high speed on an uneven road. Even the thickened pipe walls cannot prevent the metal from being strongly deformed, and even holes can form.

The legislation of the Russian Federation clearly indicates that the operation of a vehicle with a punctured muffler is prohibited.

If the driver finds that the mechanism is broken, he has only two options:

Replace with a new one. This is the easiest way, besides, you can buy a handicraft "Glushak" and put it on the car yourself.

Using a welding machine, weld a hole in the housing. This option is more costly, since it is necessary to very carefully apply welding seams so as not to burn through the muffler. In addition, the driver does not always have the skills to work with the device and you have to contact the specialists.

Operation of a muffler with a hole is prohibited.

Depending on the scale of the damage, it will be necessary to remove and replace either the entire element as a whole, or only some of it.Each operation is performed quickly and easily, the main thing is to prepare all the necessary set of tools in advance:

flat blade screwdriver;

The easiest way to perform this procedure is on an overpass or inspection pit. If possible, you can use the lift. However, most often, car owners simply raise the left rear part of the car on a jack and dismantle the muffler while lying down.

It is necessary to wait until the exhaust system has cooled down after driving, as you can easily get burned if you come into contact with hot metal. Then you can get to work:

Disconnect the main "muffler" from the resonator. To do this, you need to find a tie (clamp) and unscrew the fastening bolt. If the bolt does not loosen, you can spray it with WD-40 grease.

After the bolt is unscrewed, you need to remove the pipe fasteners and pull the muffler out of the resonator.

Then you can remove the hanging rubber bands - usually the main mechanism is easily released from them.

The main muffler is completely dismantled; you need to pull it out from under the car.

Stuck and rusted bolts can delay the dismantling process.

We will proceed from the fact that the main "glushak" has already been removed, since to dismantle the resonator, it will need to be removed:

Disconnect the resonator from the receiving tube. To do this, you need to unscrew two bolts.

If the bolts are corroded, WD-40 grease can be used again.

After unscrewing, you need to raise the resonator and disconnect the product from the suspension rubber bands.

If the rubber bands cannot be removed, you can pry them off with a flat screwdriver.

Then you can pull the resonator barrel out from under the car.

To remove the resonator from the rubber bands, just slightly raise its body and remove the pendants from the hooks

This part of the exhaust system almost never fails. It connects directly to the exhaust manifold, so before dismantling, you will need to jack the front of the machine:

All nuts are disconnected from the collector, which fix the pipe to it.

The catalyst is carefully removed from the rubber mounts.

The only thing that can cause difficulties is loosening the nuts at the inlet to the manifold. Since they are close to the motor, they heat up more than the fasteners on the resonator or muffler. Therefore, the nuts can simply stick to the metal.

The catalyst is very rarely dismantled, since it usually does not burn out and does not deform throughout the entire period of vehicle operation

The installation of a new product must be carried out in the reverse order of removal. Usually there are no problems with this procedure. However, the car owner should know the basic nuances of replacement:

It is imperative to change the reinforced seals in the system.

It is also advisable to replace the suspension rubber bands with new ones, however, in general, the replacement is carried out at the discretion of the owner (if the suspensions remain elastic and do not have cracks, then they can still be used).

To replace all bolts, it is recommended to buy products made of bronze and other heat-resistant materials. All parts of the muffler are heated, so the bolts and nuts must be as reliable as possible, otherwise they will stick to the metal after the first trip.

The dual exhaust system is not typical for VAZ 2108-2109 cars. However, if you dilute the muffler on two sides, then you can achieve quietness and more efficient engine operation.... Although not all VAZ drivers agree with this thesis:there is no use from the exhaust, if the money has nowhere to go, it is better to buy good shock absorbers. there is at least some benefit from them, comfort and safety. and if you just need sound, weld the middle resonator from 08 instead of your back can. that's all tuningThe double muffler really gives the car a more solid look. In addition, the wear of the pipes will not be so fast, since two devices are in operation at once. It is recommended to weld on the second exhaust pipe immediately after the resonator and lead it out to the right side of the bumper.It is better to entrust welding work to professionals, since the quality of the exhaust will also depend on the quality of the welding.You can hook a new muffler with rubber pendants - again, you will need to weld the hooks to the bottom in order to hook the mechanism on them. Some car owners make special rubber blocks that include mufflers, avoiding the hassle of rubber bands. This is a more reliable way of wiring two "glushak", although it requires a lot of investment. Image - Do-it-yourself muffler repair on a VAZ 21099

In this case, double nozzles are used for each muffler.

Thus, every owner of a VAZ 2108-2109 will be able to easily identify malfunctions in the exhaust system and replace the muffler with a new one without contacting a service station. By the way, drivers of "eights" and "nines" are advised to prepare in advance for problems with mufflers, as they will often fail.

A faulty muffler on cars of the VAZ 2108 and VAZ 2109 line can become a source of headache for the driver. Both literally and figuratively. It’s not good for a car engine to roar like a jet turbine. And the exhaust of such a car becomes more toxic. Can a broken muffler be repaired by myself? Of course: it's easier to do than it sounds.

It should be noted right away that the mufflers of the VAZ 2108 and VAZ 2109 cars practically do not differ from each other in design. The only difference is the size: the exhaust pipe on the "nine" is 8 cm longer.

Muffler for VAZ 2109, the body is made of stainless steel

The muffler on VAZ 2109 and 2109 cars consists of two parts:

main muffler;
additional muffler (aka resonator).

The main muffler body has the shape of an oval tube and is made of alloy steel. The housing contains a number of baffles that form the resonator compartments. There are also two tailpipes (outlet and inlet) and a main exhaust pipe. All these elements are connected by means of rolling. Spot welding is practically not used in such devices, so as not to reduce their corrosion resistance.

The muffler device for the VAZ 2109 is practically no different from the VAZ 2108 muffler

The resonator housing is a round tube with an aluminum coating. Inside there is another pipe with holes, at the ends of which there are fastening flanges. With their help, the resonator is connected to the gas receiver of the car.

It is easy to understand that the muffler of a VAZ 2109 car is faulty:

the volume of the engine increases sharply, the engine begins to growl;
at the same time, the engine power is reduced by two, or even three times;
the cabin smells like exhaust fumes;
if the driver does nothing, the roar of the engine is replaced by a deafening roar, which can sometimes be accompanied by popping, similar to pistol shots.

All this suggests that a hole has formed in the muffler housing. If nothing is done with it, then problems are inevitable:

If the muffler is faulty, the carbon dioxide in the exhaust can be trapped in the vehicle. This gas is colorless and odorless, but causes severe headache and dizziness. And if the exposure to the dioxide lasts for a long time, it can lead to the death of the driver;
Driving with a faulty muffler cannot be called comfortable;
Driving with a faulty muffler is expensive: there are rules that limit noisy driving. Violation of these rules can result in fines.

There are several typical muffler breakdowns faced by the owners of VAZ 2109 and VAZ 2108 cars:

Replacing a muffler on VAZ 2109 and VAZ 2108 cars always begins with the selection of the necessary tools and materials. Here's what we need to get started:

new muffler;
set of open-end wrenches;
ratchet socket set;
pliers;
flashlight.

In order for the result of the work to please the car owner, it is advisable to act according to the following algorithm:

The car is installed on the inspection pit. The engine is turned off, wheel chocks are placed under the wheels.
The muffler tube is disconnected from the resonator tube. To do this, the nut on the clamp is held with an open-end wrench of 13, and the bolt from below is unscrewed with a socket head with a ratchet. The clamp on the VAZ 2109 muffler is unscrewed with only two keys
The clamp, released from the bolt, is slightly unbent with pliers and removed. Before removing the muffler clamp, the VAZ 2109 is unbent with pliers
The muffler is held under the floor by a rubberized suspension system. There are three hanging hooks on the muffler body. To remove the muffler, it must be slightly raised so that all the hooks are disengaged (usually a characteristic click is heard at this moment). To remove the VAZ 2109 muffler from the suspensions, its body is raised
The muffler removed from the suspensions is removed from under the car. The muffler removed from the suspensions of the VAZ 2109 car
In place of the old muffler, a new one is installed. All assembly operations are performed in reverse order.

When installing the "muffler", you should pay attention to the reliability of the connections and make sure that it is correctly fastened under the bottom of the car.

Before describing the assembly process of a double muffler, I would like to note that in order to successfully carry out such an assembly, the driver needs to be able to work with a welding machine. If you do not have such skills, it will be much easier to buy a ready-made double muffler for a VAZ 2109 in a specialized store. Image - Do-it-yourself muffler repair on a VAZ 21099

To mount the muffler, follow the sequence of operations:

Video (click to play).

Replacing the muffler is not a big deal, even for a novice driver. All that is needed for this is a viewing hole, a couple of keys and a little patience. But the repair of this device is almost always associated with welding. And if the car owner does not have such a skill, then it will not be possible to do without the help of qualified auto mechanics.
