The exhaust system is an essential component of your vehicle that is exposed to high thermal and mechanical stresses during its service life. The high temperatures of the exhaust gases, which can exceed 900 degrees, as well as their acidity attack the internal metal walls of the pipes, silencers, catalytic converters and lambda sensors. Moisture, road salt and dirt also lead to external damage and the appearance of rust.
