The service life of the exhaust system

The service life of the exhaust system depends on operating conditions. At movement mainly over short distances within the system to a greater degree of condensation, soot and corrosive acid, than when driving long distances with a good warm up the engine.

1. Exhaust manifold with catalyst least susceptible to corrosion as compared with other parts, because there the exhaust gases with temperatures from another +800 ?� C to +1000 ?� C.

2. The resonator and muffler exhaust gas cools, its temperature reaches 150 ... 300 ?� C. The muffler accumulates most of the condensate. It is mixed with the remnants of the combustion fuel to corrosive acids, which "eat away" the metal inside the muffler.

3. Front components of the exhaust system can be damaged by the action of thermal stress during long trips, when hot metal gets rain. This material may tear or break.

4. Spray water and fluids for processing of roads in winter contribute to corrosion from the outside. Hit by stones or hard ground also shorten the life of the system, as well as fluctuations in the suspension system of a damaged muffler.
