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-t all the components into a
complete system on your garage oor, 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 mufer 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 mufers. 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 mufer 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 t. Install the xed “X” rear legs into the mufers rst. 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 mufers 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 ne 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 t, your collectors must run parallel with your rocker panels.
7. Finish the system by making all your nal adjustments to position the x-pipe,
mufers and tailpipes. Now tighten all the clamps (Warning: tightened clamps will leave
marks in the tubing, making removal or adjustments extremely difcult) or for the best t
weld all the slip joints. The 409 stainless can be welded with your standard mig welder,
and is highly recommended when possible.
