1. Begin by placing the vehicle on a lift or four jack stands at maxi-

mum height to aid in an easier installation. To help ease the installation,

pre-fit all the components into a complete system on your garage floor,

using the diagram provided.

2. Remove the existing exhaust system from catalytic converters

back. Save your factory flanges.

3. Now, install your new components. Begin by test installing your

new tailpipes. The new resonator delete pipes will get mounted in the fac-

tory hanger located near the rear bumper. Place the tailpipe section over

the axle and slide them into the resonator delete pipes. The muffler hang-

ers will get mounted to the rear seat pans just in front of the rear. If you so

choose, custom hangers may be fabricated, let your creativity shine.

4. Now, install the mufflers. The inlet should be closest to the drive

shaft and the outlet should be towards the rockers of the car. The clamp at-

tached to the hanger at the backside of the muffler will be the only connec-

tion clamp used.

5. Next, install the x-pipe. You must re-use your factory flanges

which will connect the front legs of the x-pipe to you catalytic converters.

Trimming of the front legs may be required to make sure the “X” is centered

under the drive shaft. Also, the center plate in the “X” has an arrow stamp

which must point forward. Now, slide the rear legs of the x-pipe into the

mufflers.

6. Finish the system by making all your final adjustments to position

the mufflers and piping. Now tighten all the clamps or for the best fit weld

all the slip joints. The aluminized steel can be welded with your standard

mig welder.

Now it’s time to fire up that muscle car and enjoy your

new Pypes Performance Exhaust.
