Muffler and Tailpipe





Removal

NOTICE: Do not use oil or grease-based lubricants on the insulators. They may cause deterioration of the rubber.

NOTICE: Oil or grease-based lubricants on the insulators may cause the exhaust hanger insulator to separate from the exhaust hanger bracket during vehicle operation.

NOTE: If replacement is not required, the production underbody catalytic converter and muffler and tailpipe assembly can be removed and installed as one piece. It is only necessary to cut the production exhaust to enable the service section(s) to be fitted. Before cutting any part of the exhaust system, check that the position of the cut is correct in comparison to the service section(s) being installed.

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Jacking and Lifting Service and Repair.
