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 starting with the tailpipe rst. Cut the tailpipe
off just behind the mufer, remove. Cut the mufer out next. Remove the pipe from the
mufer to the catalytic converter.
3. Now it’s time to install your new components. Begin by choosing the proper
after cat mid-pipe for your application. Most kits are supplied with two options depending
on cab and wheelbase. It is really simple to determine the one used without measur-
ing, the outlets of the mufer should land just under or just in front of the factory mufer
hanger on the truck. Here is a quick reference chart with approx required cutting mea-
surements:
• SDT13: no trim required. Cut the original mufer off right at the inlet neck.
• SDT16: trim required. Cut the original mufer off right at the inlet neck.
4. Install the proper mid pipe for your application. Be sure to slide the necessary
clamps on the pipe before sliding it into the mufer. With the mufer installed, the outlets
should land closely under the mufer hangers. Install 2 clamps on the outlets of the muf-
er.
5. You can now install the two over axle pipes onto the outlets of the mufer. The
driver side pipe is bent to travel around the spare tire. Install two HVH11S hangers, one
on each over axle pipe and hang in the factory rubber mufer hangers. The threaded
rod on the hanger allows for height adjustability. Snug up the clamps to hold the mufer
in place.
6. Next, install the PVT10 “S” bend tailpipe extensions. One HVH11S should
be slide over each tailpipe, adjust the threaded rods to the correct hanging height. The
passenger side hanger will slip into the factory rubber hanger. The driver side will require
the provided TPHV6 rubber block hanger to be bolted using 5/16” bolts to the frame rail
approx 18” from the rear bumper.
7. Now install the tips with the HVC21 clamps.
8. Finish the system by making all your nal adjustments to position of the muf-
er, over axle pipes, tailpipes and tips. Now tighten all the clamps and hangers in the
desired locations (Warning: tightened clamps will leave marks in the tubing, making
removal or adjustments extremely difcult) or for the best t weld all the slip joints. A
minimum of ½” of clearance should be maintained around all piping. All clamps should
be tightened to 65 ft lbs and should be checked after the rst 50 miles. The 409 stainless
can be welded with your standard mig welder, and is highly recommended when pos-
sible.
Now it’s time to re up that muscle truck and enjoy your
new Pypes Performance Exhaust.
