NOTE: Depending on vehicle weight, tire size, type of trailer hitch
and rear bumper your vehicle is equipped with, relocation of
spare tire may be necessary.
Disassembly
1. Raise vehicle and support with the proper jackstands,
leaving the rear suspension hanging.
2. Use caution around hot exhaust systems to avoid burns.
3. Use penetrating oil on all nuts and bolts.
4. Remove all nuts, bolts, and hanger lances from the rear
of the catalytic converter to the tail pipes.
5. Remove the old exhaust system from the rear working
forward towards the catalytic converter.
6. On 141” wheelbase models, remove the front frame
hanger bracket to facilitate disassembly (not necessary
if you are cutting the old system off).
Assembly
1. Re-install front frame hanger bracket on 141”
wheelbase models.
2. Place 3” band clamps on intermediate pipe ends and
slip onto catalytic, aligning the notch with the key on the
catalytic outlet.
3. Slip muffler onto the intermediate pipe.
4. Use the rear tailpipe lance on the muffler as illustrated.
The muffler lance will be switched to the rear to hang
the tailpipe assembly.
5. Attach axle pipe to muffler using two gaskets and 3/8”
nuts, bolts, and lockwashers.
Please study these instructions carefully before installing your new Cat-Back Exhaust System. If you have any questions, please
contact our Technical Hotline at: 1-800-416-8628, 7:00 am to 5:00 pm, Monday through Friday, Pacific Standard Time or e-mail
us at [email protected].
WARNING: Exhaust gas contains carbon monoxide, a deadly invisible gas. Correct any leaks before driving!
6. Attach tailpipes to the axle pipe using the two 2-1/2”
band clamps. Hang the right side on the stock lance
using the stock bolt. If a height adjustment is needed,
use the small two-hole bracket and the 7/16” head bolt
to drop the tube for bumper clearance. Hang the left
pipe on the universal hanger. Hold the pipe in position
and align the hanger strap with a slotted hole in the side
of the frame rail behind the shock absorber. Select the
hole in the strapthatgives the best clearance, then bolt
to frame. Use the large washer (supplied) to bolt the
strap to the frame. Use whichever hole of the straps
gives you the best alignment.
7. The small two-hole brackets are for the final adjustment
of tail pipe-to-bumper clearance, and may not be
needed in some applications. In most cases, use the
short bracket on the muffler hanger and the long
bracket on the tail pipe hanger.
8. Install tail pipe tips (not illustrated) using supplied band
clamps. We also recommend a small tack weld to
secure tips to tail pipes.
9. The factoryinstalled bumper may varyas much as 3/4”
in height. You may want to adjust your bumper for
optimum appearance.
10. Check for clearance to body, frame, and driveline as you
tighten the system from front to rear.
11. Check for leaks and correct, if anyis found.
