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. Remove the existing exhaust system from the headers or exhaust manifolds
back.
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 determine the
approximate location to mount them. The tail pipe 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. 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 attached to the hanger at the
backside of the muffler will be the only connection clamp used.
5. Next, install the x-pipe. This is where trimming of the tubing may be required
for the optimum fit. Install the fixed “X” 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 system 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
reducers) utilizing the two 1ft collector extension pipes. Trimming the length may be
required. Do not connect the x-pipe directly your headers. If down pipes (see down-pipe
instructions) 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, your 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.
