Overview - Muffler

WARNING: This page is about a different car, the 2023 Volkswagen Atlas. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

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

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

Replace the self-locking nuts.
