INSTRUCTIONS:
NOTE: do not tighten any clamps or nuts and bolts until the last
step!! Before cutting any pipes it is a good idea to lay out all
the included pipes along side the vehicle and get a good idea of how
the pipes will hang on the vehicle. Please read the instructions
fully and thoroughly before you begin.
1) Remove the exhaust system by cutting the muffler off of the
pipe that runs from the muffler to the converter. You will need
to cut the pipe as close to the inlet of the muffler as possible.
If there is an O.E. hanger immediately in front of (less than 2”) the
muffler, cut the pipe just in front of this hanger and remove the
hanger from the vehicle.
2) Two extension pipes with flanges have been included that will
fit two different models of this vehicle. One has a 2-1/4” inlet
and the other has a 2-1/2” inlet. In general, but not in all
cases, 4 cylinders will use the 2-1/4” pipe and clamp, and the V-6
models will use the 2-1/2” pipe and clamp. Install the slip-fit
end of the appropriate extension pipe to the existing pipe after the
converter, using the appropriate 2-1/4” or 2-1/2” clamp. the
appropriate extension pipe will slide over the existing pipe after the
converter.
3) Right above the connecting point of these two pipes will be a
rectangular box support beam. You will need to install the THU900
swinger hanger to this beam, and to get it to fit, you will need to put
a 90 degree bend in the middle of the metal strap for clearance.
If no convenient hole is present in the beam, drill a 3/16” hole in
this beam (but not through the box!) directly above the connecting
point of the two pipes. Use a 5/16” x 1-1/4” lag screw and fender
washer and install to the support beam. Use the clamp used in
step 2) to clamp the THU900 swinger hanger to the connecting point of
the two pipes.
4) Install the flanged end of the y-pipe to the flanged end of
the extension pipe using the 3/8” x 2-1/2” bolts, nuts, and lock
washers.
5) Remove the O.E. hangers that are on the vehicle above the end
of the y-pipe and at the end of the tail pipe. Install the i.d.
end (inlet) of the right tail pipe to the y-pipe and use a 2-1/4” clamp
to connect the two pipes. Install an LB7 metal hanger to the
frame near where the rear O.E. hanger was. Use the existing bolt
hole if possible, or drill a 5/16” hole in the frame after the rear
axle but before where the tips will be. The grommet will snap
around the short part of the LB7 hanger. Install a 5/16” x 1”
bolt, nut, and lock washer to the hanger assembly and bolt to the
frame. Use a 2-1/4” clamp t connect the right tail pipe and the
hanger assembly.
6) Install the i.d. end of the left tail pipe to the
y-pipe. The left tail pipe is routed over the rear differential
and behind the rear shock. Directly above the junction of the
left tail pipe and the y-pipe is a cross member. Locate or drill
a 3/16” hole in this cross member and install the long end of the BR1
hanger bracket using a 5/16” x 1-1/4” lag screw and fender
washer. Use a 5/16” x 1” bolt, nut, fender washer, and lock
washer to connect the THU400 rubber hanger to the BR1 bracket.
Use a 2-1/4” clamp to connect to the left tail pipe just after the i.d.
end of the left tail pipe.
7) As in step 5), install the rear hanger to the frame (drill
another hole if one is not present) and clamp to the right tail
pipe. The hanger should be placed about as far back as the hanger
in step 5).
8) Those with long boxes, you will not need to cut off the tail
pipe length. those with short boxes, you will need to cut your
tail pipes as necessary. Hold up a tip next to a tail pipe with
the desired length of the tip sticking out the rear of the
vehicle. Mark the tail pipe and be sure to account for 3” of the
tip that will slide over the tail pipe. Trim the tail pipe as
necessary and repeat as necessary and repeat for the other tail pipe.
9) Install the tips to the tail pipes using 2-1/4” clamps.
10) Tighten all clamps, nuts, and bolts. Check for
clearance of all brake and fuel lines, and for clearance of all chassis
and frame components. For detailed installation pictures-email at
