The exhaust system consists of a front exhaust pipe with a catalytic converter, a middle silencer and an end silencer. Lambda probe required for catalyst control (only petrol engines), screwed in front of the catalyst.
The catalyst is fixed together with the engine exhaust manifold. When repairing, parts can be replaced individually. Nuts and gaskets must be replaced after removal. Mounting rings and rubber buffers must be checked for damage and replaced if necessary.
