1. Begin by placing the vehicle on a lift or four jack stands at maximum 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. First, remove the existing exhaust system from the headers or exhaust manifolds
back. You can also remove any hangers mounted to the frame as your new kit includes
factory reproduction hangers.
3. Now it’s time to install your new components. Begin by test installing your new
tailpipes. Since this system uses universal style hangers, you will need to find an ap-
propriate location to mount them. The tail pipes hangers will mount to the outside of the
frame rails just behind the rear tires. The muffler hangers will get mounted to the rear seat
pans just in front of the rear. On the Pontiac models, you will be able to utilize the factory
tailpipe hangers mounted to the inside of the frame rails. If you so choose, custom hang-
ers 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 attached to the hanger at the
backside of the muffler will be the only connection clamp used.
5. Next, its time to install the x-pipe. This is where trimming of the tubing may be
required for the optimum fit. Install the rear legs into the mufflers first. You are aiming to
have the center “X” land approx 8-12 inches behind the tail shaft of your transmission and
centered under the driveshaft. Also, the center plate on the “X” has an arrow stamp which
must point forward. Trim the rear legs as needed to put your “X” and mufflers in the proper
location. Quick tip: If the rear suspension is unloaded, you can push the center “X” up
until it just about touches the drive shaft as it will never hit once t he suspension is loaded.
Slide the front legs into the x-pipe. They should end somewhere close to the humps in
your transmission cross-member. On some applications, the front “X” legs may not be
centered in the humps but line up to your headers or down-pipes. This is fine as the sys-
tem will not hang too low. Be extra careful when measuring and cutting. A helpful tip: Line
up the front legs under the center “X” to mark your cut lines making sure to line them up
with you headers or down pipes.
6. Continue by connecting the front legs of the x-pipe to the headers (collector re-
ducers) utilizing the two 1ft collector extension pipes. Trimming the length will be required.
Do not connect the x-pipe directly your headers. If down pipes (see down-pipe instruc-
tions) are used, make sure the pipe ends close to the rear side of the transmission cross
member. If they are too long they must be trimmed. Some header applications require
custom collectors due to the header not ending square and parallel to the car. For proper
system fit, you collectors must run parallel with your rocker panels.
7. Finish the system by making all your final adjustments to position the x-pipe,
mufflers and tailpipes. Now tighten all the clamps (Warning: tightened clamps will leave
marks in the tubing, making removal or adjustments extremely difficult) or for the best fit
weld all the slip joints. The 409 stainless can be welded with your standard mig welder,
and is highly recommended when possible.
Now it’s time to fire up that muscle car and enjoy your
new Pypes Performance Exhaust.
