Removal of the factory exhaust system is the first step. With the vehicle supported by either jack stands
or a lift loosen the factory butt connect clamps located where the factory down pipes end and the cat
back system begins followed by the 13mm bolts that hold the hangers closed to the differential.
If your vehicle is equipped with active exhaust make sure to disconnect the plugs to the servo motors.
Once all the about is complete you can fully remove the system from the car.
Place the Pypes resonator delete pipe on top of the factory exhaust and mark where the cuts need to Place the Pypes resonator delete pipe on top of the factory exhaust and mark where the cuts need to
be made. Make sure your cut marks compensate for the slip fit joint at the rear of the delete pipe and
that the delete pipe follow the path of the stock exhaust closely. Note there is a top and bottom so fol-
lowing the factory exhaust path is critical to making the right cuts.
Once you are confident that your makes are in the right place cut the factory exhaust system along
those lines. Cut as square as possible and deburr any sharp edges after the cutting process. If your
factory exhaust is equipped with heat shields, they must be removed where they interfere with the
delete pipe shipping onto the stock system.
Begin the reinstall with the cut factory sections by placing the muffler wire form in the rubber hanger at
the back bumper followed by the hangers at the rear differential. Do not tighten completely at this time.
The Pypes Resonator Delete pipe is next. Using the supplied HVC21 clamps slide the expanded end of The Pypes Resonator Delete pipe is next. Using the supplied HVC21 clamps slide the expanded end of
the pipe over the factory cut tailpipes followed by the factory butt clamps connecting the front of the
delete to the factory down pipes.
How that all the components are installed you can align the system and tighten all the clamps and
hangers. Make sure to reconnect the plugs for the active exhaust if your car is so equipped.
