REMOVAL
WARNING: The normal operating temperature of the exhaust system is very high. Therefore, never attempt to service any part of the exhaust
system until it is cooled. Special care should be taken when working near the catalytic converter. The temperature of the converter rises to a
high level after a short period of engine operation time.
WARNING: If torches are used when working on the exhaust system, do not allow the flame near the fuel lines.
CAUTION: When servicing exhaust system components, disconnect the oxygen sensor connector(s). Allowing the exhaust system to hang by the
oxygen sensor harness will damage the wiring and oxygen sensor.
All original equipment exhaust systems are manufactured with the exhaust tailpipe welded to the muffler. Service replacement mufflers and exhaust
tailpipes are either clamped together or welded together.
1. Raise the vehicle and support the rear of the vehicle by the side rails and allow the axle to hang free.
2. Remove the tailpipe hangers from the insulators.
3. Remove muffler to catalytic converter flange retaining nuts.
4. Remove muffler and tailpipe assembly from vehicle.
