The exhaust system’s function is to safely remove hot exhaust fumes from the engine’s combustion chamber outside of the vehicle. It also reduces the noise generated inside the combustion chamber. The exhaust system’s integrated catalytic converter changes noxious substances present in the exhaust fumes to substances which are almost harmless to health.

Wear and corrosion
Therefore have exhaust system checked in particular for leaks and its attachments! In each inspection only new seals must be always used.
