Here at American Muscle, we're all about DIY (do it yourself). Of course, there's nothing wrong with seeking out a little bit of tech help prior to taking on an installation on your own. Our Mustang installation guides will provide valuable instructions and hopefully answer any how-to questions that you may have along the way.

Please read through the instructions carefully before starting this project.  Take the time to get all the materials together as well as all the safety equipment.

When working on, under or around any vehicle, exercise caution. Please allow the vehicle's exhaust system to cool before removal, as exhaust system temperatures may cause severe burns. If working without a lift, always consult vehicle manual for correct lifting specifications. Always wear safety glasses and ensure safe work area. Serious injury or death could occur if safety measures are not followed.

Installation:

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. Begin removal of the OEM system by loosening the band clamps that fasten the muffler and over-axle pipe to the catalytic converter. Unbolt the mounting brackets that mount the muffler to the frame, and remove the muffler assembly. Do not discard the OEM mounting brackets or fasteners as they will be reused to mount the new mufflers. You can now remove the over-axle pipe as well







2. Install the OEM rear muffler bracket on the hanger of the new passenger-side muffler assembly, and install the OEM front muffler bracket on the driver-side muffler assembly. Fasten the Y-pipe assembly to the catalytic converter re-using the OEM clamp. Leave all clamps and fasteners loose for final adjustment of the complete system. Install the new over-axle pipes using the supplied 2.50" clamps. Install the muffler assemblies using the supplied clamps, and by bolting the mount brackets to the frame using the OEM fasteners. See Diagram 2 for more detail on mounting the passenger's side muffler. No drilling is required, the holes are already set up from the factory.





3. With all components mounted loosely, adjust the system for overall aesthetics and clearance of frame & bodywork. (MANGAFLOW 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 after 25-50 miles of operation, and re-tighten if necessary.
