Installation

1. To begin removal of your OEM exhaust system you will need to cut the tail-pipes just behind the mufflers. Remove the tail pipes from the rubber insulators. Do not damage the rubber insulators, as they will be reused with your new system. Next, unbolt the extension pipes from the H-pipe and remove the mufflers from their OEM rubber insulators. Do not discard the fasteners required to bolt the extension pipes to the mufflers, as they will be re-used.


2. Begin installation by bolting the new front extension pipes to the H-pipe with the supplied flanges and the OEM fasteners. Leave all components loose until a final position is chosen for aesthetics and clearance. Working rearwards, slip the new mufflers over the ends of the extension pipes and mount the muffler hangers into the OEM rubber insulators. Slip the tail pipe hangers into the OEM rubber insulators. Slide the tips onto the tail pipes, and fit the tip hangers into the OEM rubber insulators under the rear fascia.



3. Adjust all components for clearance of the frame, bodywork, and overall aesthetics. (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, evenly tighten all fasteners from front to rear, including OEM H-pipe fasteners, U-bolt clamps and the tip assembly fasteners to complete installation. Inspect all fasteners after 25-50 miles of operation, and re-tighten if necessary.
