Removal and Replacement

Exhaust System Overview

• The coupling element in the exhaust pipe with catalytic converter must not be bent more than 10°, otherwise it may be damaged.

• Gaskets and self-locking nuts must be replaced.

• After exhaust system repairs, make sure the exhaust system is not under stress and is far enough from the body. If necessary, loosen the clamping sleeve and align the muffler and exhaust pipe so that there is adequate distance to the body and that the weight is evenly distributed among the suspended mounts.

• The exhaust manifold and turbocharger are one component removing and installing. Refer to => [ Turbocharger ] Turbocharger.
