Car middle silencer

Centre silencer is a part of the exhaust system of the car. It is located in front of the main silencer and has a barrel-like shape. Inside it there is a receiver tube that extends to the rear silencer. The special design of the centre silencer provides a significant reduction of noise in the exhaust system. Therefore, it is easy to determine failure in this area.

If the exhaust system is running unusually loud, it could be the fault of the centre silencer. Even a small crack significantly increases the noise level. The main reason of centre silencer failure is corrosion. It is quite common in older cars. Little damages can be repaired by welding. But the best way is to install a new part. The entire exhaust system should be checked for corrosion. Often it is necessary to replace other parts. Moreover, it is necessary to replace gaskets, screws and flanges.

To install the centre silencer it is necessary partially to dismantle the exhaust system. Even a non-professional can do this work. However, before you tighten the clamps, make sure that the centre silencer and all other details are correctly mounted. Start the engine and check functionality of the centre silencer. In our online shop you will find silencers, catalytic converters, brake shoes, stub axles, spark plugs, horns, radiators, and other spare parts of high quality. We will help you to save on maintenance and repair. This is a forcible argument to visit our Internet shop.

Middle silencer failures

• housing surface defects;
• burning-out of the element;
• functional characteristics worsening;
• perforated pipes clogging.

Signs of middle silencer failures

• steady smell of exhaust gases in the passenger compartment;
• exhaust sound loudness increasing;
• strong vibration at engine rotation;
• appearance of soot traces at the car bottom surface;
• breakage of the catalytic converter or its melting;
• reduction of engine performance;
• significant increasing of the engine temperature;
• clunking during the middle silencer operation.

Causes of Middle exhaust pipe failures

• mechanical damages;
• breaking of the part metal component;
• overheating of the medium silencer;
• strong variations of temperature rates;
• inflow of moisture or oil into the system;
• road reagents impact;
• use of poor-quality fuel.

Diagnostics

Visual diagnostics of the Middle exhaust pipe can be accomplished without service station specialists assistance. It is necessary to pay attention to the presence of mechanical damages, traces of  soot, metal breaking and its oxidation. Any of these signs testifies to failure of the element. Detailed diagnostics of the resonator is carried out by skilled technicians. They check the operability of the resonator by means of the capacity and temperature rates analysis.

The service life of the silencer is 20 000 operational kilometers. The negative factors arising during operation can reduce life cycle by 50%. It is undesirable to exceed the recommended operation period. Wearing out of the spare part causes strengthening of vibration and increases the temperature of exhaust gases, thereby influencing operation of the catalyst converter.

Replacement of Middle exhaust pipe

As the component has the all-metal body, it can't be repaired. Damaging of the body integrity for repair purposes, will not lead to desired result but only worsen the condition of the part.

It is necessary to separate the middle silencer from the pipe to replace it. High temperatures may cause adhesion of the component to the fastenings. If it happened, it is necessary to use the specialized equipment and to cut off the part together with the fastenings. Resonator repair works are performed at a service station only.
