Exhaust Pipe with Catalytic Converter Overview

Exhaust Pipe with Catalytic Converter Overview

• After exhaust system work, ensure the system is spaced far enough away from the body. If necessary, loosen the double clamp on the front exhaust pipes and align the pipes again.

• Do not use sealants containing silicone. Traces of silicone which are sucked into the engine are not burned there, and they damage the oxygen sensors.

• Replace the self-locking nuts.
