Installation Notes

NOTES:
- Replacement exhaust system parts must be OEM equivalent to ensure that the vehicle operates as designed.
- When installing a new exhaust pipe or muffler and tailpipe, always check for proper alignment. Rattles and noise vibrations in the exhaust system are usually caused by misaligned parts. When aligning the system, leave all bolts or nuts loose until all parts are properly aligned then tighten, working from the front to the rear.
Exhaust system hangers, hanger brackets, and clamps which are damaged should be replaced to maintain exhaust system alignment.
- When jacking or lifting the vehicle from the frame side rails, be certain lift pads do not contact the three-way catalytic converter as damage to the converter will result. When servicing of the exhaust system requires removing and replacing the oxygen sensors, refer to Oxygen Sensor Service and Repair.
- Apply sealer to all slip joint connections.
- When replacing a muffler, replace the tailpipe also.
- When installing the exhaust pipe to the engine manifold, always use new nuts. Clean the engine manifold stud threads with a wire brush before installing the new nuts.
