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 starting with the tailpipe first. Cut the tailpipe off just behind
the muffler, remove. Cut the muffler out next. Remove the pipe from the muffler to the catalytic con-
verter.
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 measuring, the outlets of the muffler should land
just under or just in front of the factory muffler hanger on the truck. Here is a quick reference chart
with approx required cutting measurements:
• SFT13: 2-1/4” short mid pipe (MFT13A) first, then the long mid-pipe (MFT13B)
is for 133”, 138.8” and 155” WB, minor trimming required for 133” and 138.8”.
• SFT16: Use MFT16 stock length
• SFT19:
Reg Cab: 6.5’ bed 126”WB trim 11” off, 8’bed 144.5”WB no trim
Super Cab: 5.5’ bed 132.5”WB trim 4.5” off, 6.5’bed 144.5”WB no trim;
8.0’ bed 163”WB no trim add MFT19A
Super Crew: 5.5’ bed 138.5”WB trim 1.5” off, 6.5’ bed 150.5”WB no trim add MFT19A trim 15” off
4. Install the proper mid pipe for your application. Be sure to slide the necessary clamps on
the pipe before sliding it into the muffler. With the muffler installed, the outlets should land closely
under the muffler hangers. Install 2 clamps on the outlets of the muffler.
5. You can now install the two over axle pipes onto the outlets of the muffler. 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 muffler hangers. The threaded rod on the hanger
allows for height adjustability. Snug up the clamps to hold the muffler 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 final adjustments to position of the
muffler, 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 difficult) or for the best fit 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 first 50
miles. 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 truck and enjoy your
new Pypes Performance Exhaust.
