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 remove the OEM exhaust system, unbolt the clamps fastening the muffler inlets to the over-axle pipes. Unbolt the muffler hanger brackets from the frame, and remove the mufflers from the vehicle (The brackets will be reused). Remove the over-axle pipes in a similar fashion. Do not discard the OEM brand clamps or damage the OEM rubber insulators, as they will be used to mount the new system.
Remove the OEM hanger brackets from the mufflers and reattach them to the frame of the vehicle. (Make note of the hanger isolator orientation as improper installation will cause fitment issues). Leave all the clamps and fasteners loose for the final adjustment of the complete system. Fit the new over-axle pipes into place and fasten them to the catalytic converters and new mufflers using the OEM clamps at the converters and the new supplied band clamps at the mufflers.
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.)
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.
These guys are great! Customer service is absolutely top notch. Their pricing points are spot on and every month they off some sort of special on multiple parts. Not only that but the staff will educate you on the parts and their customer reveiw option of every part has been a huge help in determining the validity of each part you buy. American Muscle is the perfect example of what a full service parts distributor and custom tuning shop should be. I'm just glad they are Mustang exclusive!
