Installation

  1. To remove the OEM exhaust system, unbolt the muffler extensions from the catalytic converter H-pipe. Do not discard the OEM fasteners, as they will be re-used to mount the new system. Remove the mufflers and tailpipes from the OEM rubber insulators. Do not damage the OEM rubber insulators, as they will be re-used to mount the new system.

  3. Begin installation of the new exhaust system by bolting on the new front extension pipes using the supplied flanges and the OEM fasteners, as shown in the diagram. Leave all fasteners loose for final adjustment. Fit the tailpipes' welded hangers into the OEM rubber insulators. Install the mufflers using the supplied U-clamps. The notched inlet end of the muffler will fit over the outlet end of the front extension pipes and the notched inlet of the tailpipes will fit over the outlet end of the muffler.tailpipestips
  4. With all components mounted loosely, adjust the system for overall aesthetics and clearance of frame & body panels. (MAGNAFLOW recommends at least 1/2" of clearance between the exhaust tips and the rear fascia to avoid heat related body damage or fire.)

  5. Once a final position is chosen for the new system, evenly tighten all fasteners from front to rear. Inspect all fasteners after 25-50 miles of operation and re-tighten if necessary.
