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. 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 OEM rubber insulators. Do not damage the OEM rubber insulators, as they will be re-used with your new system. Next, unbolt the extension pipes from the H-pipe and remove the mufflers from their OEM rubber insulators. Do no discard the fasteners required to bolt the extension pipes to the mufflers, as they will be re-used.

2. Remove the existing muffler mount brackets, and replace them with the new brackets supplied in the kit. Do not discard the OEM mount fasteners, as they will be re-used. Refer to diagram #2 for installation of the new muffler mounts.

3. Starting at the H-pipe, begin installing your new exhaust system by bolting up the front extension pipes with the flanges supplied in the kit and the OEM fasteners. Working rearward, install the mufflers, tail-pipes and tips, using the supplied clamps, hangers and fasteners. Leave all components loose until a final position has been set.

4. Set the final position by checking for ground clearance, frame clearance in all areas and rear fascia clearance of exhaust tips. Once a final position has been chosen, tighten all hardware including H-pipe hardware, all U-clamps, exhaust tip clamps, and exhaust tip slide hangers. Inspect all hardware after 25-50 miles of operation, and re-tighten if necessary.
