Owner manual

1. Begin by placing the vehicle on a lift or four jack
stands at maximum height. This will aid in an easier instal
-
lation.
2. Unbolt the factory cat-back from the rear of your h-
pipe or x-pipe. If you still have a factory system on the car,
you may need to cut the mufers out of the system using
a hack saw or a saws-all. Finish by removing the tailpipes
from the rubber hangers. Be sure to check the rubber
hanger to see if they are in good shape. Old stretched
out rubber hangers will only make your new system hang
and t poorly. If new hangers are required, please contact
your local Ford dealer, or auto parts store for replace
-
ments. Pypes Exhaust only offers the rear tailpipe hangers
(TPHV6).
3. Now it’s time to install your new cat-back. Begin
with the tailpipes rst. Assemble the corresponding tailpipe
sections using the supplied band clamps. Next mount the
tailpipe wire forms into the factory rubber mounts, slide the
tips on to the tailpipes. Next, install the tip hangers through
the boss on the tip and slide the other end through the rear
hanger. Make sure to leave the clamping bolt and set screw loose until the entire kit is installed. A small amount of grease or
liquid soap will allow the hanger to slide through easier.
4. Next install the mufers on to the tailpipes. Again, a small amount of grease in the mufer inlet and outlet will allow
for easy rotation when adjusting for the perfect t.
5. Next, install the ow tube anges on to the ow tubes and slide them into the inlets of each mufer. A small amount
of grease will also help here too. The shorter ow tube belongs on the driver side of the vehicle. Once the ow tubes are in
place, you can install the bolts to connect them to your h-pipe or x-pipe. If you vehicle still has a factory h-pipe, you will just
re-use the factory bolts and nuts as the bolt is an integral part of the h-pipe. Snug the hardware just enough to allow rotation
for adjustment. Now install the four clamps on the mufer necks, snug the nuts, and DON’T TIGHTEN. Once these clamps
are tightened you will not be able to adjust any of the components.
6. Last, make all your nal adjustments for t. Make sure the mufers are parallel to the ground. Rotate the ow tubes
for the best t. Also, make sure the tailpipes/tips are positioned in the correct location under/in the rear bumper. Once you
are satised with the t, tighten all six clamps, tip clamp, hanger set screw (a small weld tack is recommended where the tip
hanger slides into the tip boss to maintain alignment) and the connection points at the h-pipe. Air tools will allow the tightest
clamping possible. Now it’s time to re up your Mustang. Remember to listen and check for exhaust leaks. Also, periodically
check all connections points as they may come loose.
Now it’s time to re up that muscle car and enjoy your
new Pypes Performance Exhaust.
