1. Disconnect the vehicle's battery before removal of the OEM exhaust. This will allow the computer to reset itself with the new system and prevent electrical accidents. Loosen the clamp that attaches the OEM muffler inlet to the over-axle pipe. Disengage the welded hangers from the rubber insulators, and remove the muffler assembly taking care not to damage the rubber insulators.

2. Before installing the new muffler assembly, slide the supplied 2.50" clamp onto the inlet pipe. Install the new muffler assembly by fitting the welded hangers into the rubber insulators, and by fastening the muffler inlet to the over-axle pipe using the supplied clamp. Be sure to line up the large notch in the inlet pipe with the alignment peg on the over-axle pipe, or the muffler will not fit properly.

3. With all components mounted loosely, adjust the system for overall aesthetics and clearance of frame & bodywork. (MAGNAFLOW recommends at least 1/2" of clearance between the exhaust tips and the rear fascia to avoid heat related body damage or fire.)

4. Once a final position has been chosen for the new system, evenly tighten all fasteners from front to rear. The supplied band clamps must be VERY tight to properly align the pipes and prevent leaks (Approximately 65 ft-lbs). Inspect all hardware after25-50 miles of operation, and re-tighten if necessary.
