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 repair or install any new part of the system until it has cooled. Be especially careful when working around the 3-way catalytic converter. The temperature of the 3-way catalytic converter rises to a high level after only a few minutes of engine operation.

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

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

NOTE: Exhaust fasteners are of a torque prevailing design. Use only new fasteners with the same part number as the original. Torque values must be used as specified during reassembly to make sure of correct retention of exhaust components.
