Muffler: Service and Repair

Muffler and Tailpipe

Removal and Installation

WARNING: The normal operating temperature of the exhaust system is very high. Never attempt to service any part of the system until it has cooled. Be especially careful when working around the catalytic converter. The temperature of the catalytic converter rises to a high level after only a few minutes of engine operation.

CAUTION: Do not use oil or grease-based lubricants on the isolators. They may cause deterioration to the rubber.

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