Silencer VAZ-2115: description, specifications and device

Cars of the family "Lada-Samara 2" became a continuation of all known "nines" and "eights", which were produced since the time of the USSR. As for the particular model 2115, it is a continuation of the "ninety-ninth", the release of which lasted more than twenty years. In the car "Samara 2" used a lot of detail from the old "Samara". The exhaust system also passed here. However, its device and the principle of operation does not differ from the one that stands on foreign cars. Well, let's look at the VAZ-2115 silencer in more detail and find out how to change it.

Appointment

This element is part of the exhaust system. Its purpose is to release exhaust gases from the cylinders of the power unit. In addition, vibrations are suppressed inside the silencer. Thus, the exhaust becomes quieter.

Where is

The silencer VAZ-2115 is located under the bottom and is the final element of the exhaust system.

But this is not the only part of this system. In front of him there is a resonator muffler. VAZ-2115 is equipped with them without fail. Through it also pass the exhaust gases.

Varieties

It is worth noting that this car has two types of mufflers:

• Preliminary.
• Main.

The first is a resonator. It consists of a metal body, blinds and perforated tubes. Also inside the resonator there is a thermal insulation. This element is connected directly to the intake pipe. As for the main one, this muffler on the VAZ-2115 (the price of which, by the way, is 900 rubles) serves as a function not only of the heat sink, but also of damping the sound vibrations. The device of this element assumes the following details:

• Front perforated pipe.
• Middle and back septum.
• Outlet and inlet branch pipe.

All this is neatly housed in a metal casing. Sometimes the corrugation is placed between the intake pipe and the silencer.

Gofra

This element is installed on many cars of both domestic and foreign production. VAZ-2115 is no exception. Gofra performs vibration damping function. Since during the combustion of the fuel-air mixture the gases burst outward with great effort, the exhaust sound would be very loud. Gofra partially reduces the noisiness of the exhaust gases. It is made of stainless steel. It is very flexible. Unlike a silencer and a resonator, the corrugation does not rust. However, it is subject to mechanical damage. Since it is located under the bottom, it often clings to the asphalt. As a result, it deforms and passes through the gases.

Corrugation repair

Can I restore it? Gofra, unfortunately, is not being repaired. It can not be replaced without special tools. It is welded into the exhaust pipe. There is an element inexpensive. Most of the costs will be for welding.

Features of the pre-muffler

This element is the middle part of the exhaust system. Performs the function of "mirror", reflecting the air flows of gases that come from the combustion chamber. Unlike the main one, the additional VAZ-2115 silencer (resonator) does not have several tubes. Here she is alone, and also perforated. The resonator is a kind of acoustic mirror.

Symptoms of muffler malfunction

How to determine that the element has become unusable? Everything is very simple. If the car began to "yell" even at low speeds, then there is a breakdown in the hull. Usually the VAZ-2115 silencer burns from the inside. At the same time, the sound of the exhaust changes. He becomes loud and irritable. Also note that faults can not only affect this element. If a muffler was replaced (VAZ-2115 including), and the car did not change its tone, it means that the breakdown is in a different place. Check the state of the corrugation or resonator. They also have the property of burn out.

This is due to high exhaust gas temperatures . Plus, the lack of additional protection. The exhaust system is not protected from dirt and water, which gets to the bottom. Of course, all this significantly accelerates the corrosion process. In the winter, it is still worse - salt and road reagents accelerate the decay of the exhaust system elements dozens of times. If after the winter the exhaust of your car has become loud, it is worthwhile to climb the overpass and inspect which particular element of the exhaust system has failed. And only after that buy a new one. It is not recommended to buy products from foreign manufacturers. This is cheating - you will get a Chinese counterfeit. It is better to trust the domestic manufacturer and buy the Togliatti elements.

How much does the muffler cost for the VAZ-2115?

The average price of this element is 800-1000 rubles. How much does the resonator cost (additional muffler on VAZ-2115)? Its price is almost the same as for the main one - 1050 rubles. But in addition to the elements of the exhaust system, you need to purchase additional gaskets. The best silencer VAZ-2115 - produced by Togliatti. Also inspect the condition of the pillows. If necessary, buy a new set.

Replacement of muffler

To install this element, unlike corrugation, you can and with your own hands. For this we need a lift, a flyover or an inspection pit. Next, we find the crimp clutch and twist it with a ratchet (you can use the carabiners). If the bolt starts scrolling, hold its second side with an additional key. If the collar is fairly rusty, you can use the lubricant in the can (VD-40). After waiting a couple of minutes, we proceed to dismantle. Removing the collar, we find inside the O-ring.

We do not throw it away, but install it on a new one. Remove the muffler from the rubber cushions. If the elements have cracks, we change them. On cars "Lada-Samara" of the first and second generations rubber cushions are very thin. They do not stand the weight of the muffler and often break off.

What next?

After dismantling the old one, install a new silencer in the reverse order. In order not to suffer from the installation, first fix the element to the cushions, and then attach it to the clamp. Do not forget about the O-ring. We put it between the exhaust pipe of the resonator and the intake pipe of the silencer.

Replacement problems

Most often, problems arise when the old element is dismantled. It simply sticks to the resonator. Sometimes bolts break off. In this case, you can apply the Bulgarian. But you need to act carefully, so as not to hook the resonator. If the latter also has become worthless, the problem with dismantling does not go away. Through the chain, the resonator likewise adheres to the receiving tube. If they change, they should be stocked with the gasket, which we mentioned earlier. It looks like this.

This part squeezes the intake pipe with the collector and does not allow exhaust gases to leak out. Thanks to the gasket, they follow the pipe strictly - to the muffler, and further to the street. There is also a problem with unscrewing the bolts. If they do not "go," they are also cut off by the Bulgarian. They are replaced by new ones.

Helpful advice

In order to avoid further problems with dismantling the muffler and resonator, it is recommended that the threads of the bolts be treated with grease. This is "Litol-24" or ordinary graphite. Lubricant repels water well. Accordingly, you reduce the risk of corrosion.

Can I ride without a bump?

Often car owners "cut out" it from the system and travel on a straight pipe, installing an elongated resonator. Damage to the engine does not do this. The only thing is that the exhaust noise will increase slightly.

Conclusion

So, we found out what the VAZ-2115 silencer is. This element takes on all the toxic and temperature loads.

Therefore, with frequent use, it becomes an expendable material. The term of his service is about two years. In addition, it is not necessary to treat it with the purpose of corrosion protection. All paint and movile will not withstand such temperatures. And the price of an element is not that high to think about additional means of protection.
