Installing the High-Flow Cat-Back Exhaust

• To begin the install, slide the front section of the new exhaust onto the stock cats (figure D), using a jack to support the pipes (figure E) while replacing the nuts. Leave the nuts a little loose for adjustment until all of the pieces are in place.

• Pop the new hardware into the flange on the backside of the H-pipe, and slide the supplied gasket onto the bolts (figure F).

• The intermediate pipe snakes in over the cross member, then start it into the factory rubber hanger.

• Some lubricant will help the hanger slide over the flange that holds it in place (figure G), and then it can be connected at the front end.

• Since the old system only had one pipe, there are no hangars on the passenger side. A good quality exhaust system will come with the extra parts you need.
  Bolt the new bracket into place, and slide the rubber piece onto the post.

• The passenger side intermediate pipe goes in next. Snug it up at the H-pipe and hook it into the hangar.

• At the back, add in the mufflers and tailpipes, which slide over the ends of the intermediate pipes (figure H).
  

  Clean fingerprints and smudges from new chrome exhaust before you test drive.

• Now that all of the new parts are in place, go back to the front of the car and tighten up everything, using the jack stands to hold the exhaust system up against the underside of the car while locking it down.
