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 old exhaust system, leaving only the y-pipe and the
converter on the truck, keeping the o.e. rubber hanger mounts in place.
2) Install the 2-1/2” i.d. end (shrunk end) of the 3” front
extension pipe to the converter using a 2-1/2” clamp. Be sure to
line up the notch on the extension pipe to the knob on the
converter. This extension pipe will need to be cut (from the 3”
o.d. end) to length for wheel bases shorter than 141”. For 117”
wheel base, cut to 19-1/2”, for 133” wheel base, cut to 33-1/2”, for
155” wheel base, use the full length of this extension pipe plus the 3”
x 17” id/od extension pipe.
3) Install the y-pipe to the 3” extension pipe (the leg with the
bend goes towards the drive shaft), using the 3” hanger clamp to
connect the two pieces. (note: on some vehicles, you may need to
use the 3” hanger clamp in another location. Use the 3” clamp if
necessary, some vehicles will not require it.) Locate the
original hanger mount located above and along side the 3” front
extension pipe and y-pipe. Install the 3” hanger clamp to the
o.e. hanger and connect the clamp to the 3” front extension pipe.
4) Install the right tail pipe (it has 5 bends) to the y-pipe
using a 2-1/4” clamp. Make sure that you have at least 1/2” of
clearance from the shock.
5) Install the right tail pipe extension to the right tail pipe
(it is the short 2-1/4” id/od piece). Use the 2-1/4” hanger clamp
to connect the right tail pipe and the right tail pipe extension.
Connect the hanger to the o.e. mount above this connection point.
NOTE: you may want to trim the right (and later the left) tail
pipe to your desired length, short box models will require this step.
6) Install the muffler tip onto the right tail pipe. Use a
2-1/4” clamp to secure the tip to the tail pipe and hanger just
installed.
7) Install the left tail pipe (4 bends) to the y-pipe.
There is a cross-member above this connection point. You will
need to drill a 5/16” hole in this cross-member. Take a BR91930
swinger hanger and bend the top portion at a 90 degree angle after the
first hole. Install this hanger to the cross-member using the lag
screw. Use a 2-1/4” clamp to connect the hanger to the junction
of the left tail pipe and the y-pipe. The left tail pipe is
routed between the shock and the spring.
8) Install the left tail pipe extension (long) to the left tail
pipe using a 2-1/4” clamp. Again, you may want to trim the pipe
to length.
9) Locate the hole in the frame on the left side after the rear
axle (or drill if one is not present), and install a BR91930 hanger to
the frame using the included 5/16” x 1” bolt, nut, lock and fender
washer. This hanger will be used on the left tail pipe extension
between the front clamp and the tip. Use a 2-1/4” clamp to
connect the hanger and the left tail pipe extension.
10) Mount the other muffler tip to the left tail pipe using a
2-1/4” clamp. Secure the tip to the tail pipe and the hanger as
done in step 6).
11) Tighten all clamps, nuts, and bolts. Check for leaks
and for clearance of all brake and fuel lines, and for clearance of all
chassis and frame components. We recommend tack welding the
joints (not necessary though).
