5. Locate the driver and passenger side axle pipe adapterS along with two 3” clamps for each axle pipe adapter.
Identify the adapter inlet and outlet sides. The inlet side will have visible clamp marks/rings (Fig. Q) while the
outlet end will have a smooth finish. (Fig. R.) Install the clamps on both ends of the adapters so that when the
adapters are installed in the vehicle, the clamp bolts are perpendicular to the ground and the nuts are facing
towards the ground. The Passenger side bolt clamp should be towards the passenger side of the vehicle and driver
side bolt clamp should be on the driver side. Starting with the passenger side adapter, slide the expanded inlet
end of adapter pipe over the passenger side muffler outlet pipe. Snug the clamp at the muffler connection point
using a 15mm deep socket and ratchet. (Fig. S) Next, slide the expanded inlet end of the driver side adapter over
the driver side muffler outlet pipe. Snug the clamp at the muffler connection point using the 15mm deep socket
and ratchet. Leave the outlet clamps loose at the time.
6. Locate the stock driver side tailpipe assembly. Snake the assembly around the spare tire and over the rear
differential and slide the tailpipe inlet end into the expanded outlet end of the driver side adapter. (Fig. T) Next,
slide the rear tailpipe hanger grommet assembly against the vehicle frame, insert the threaded stud assembly from
the rear of the vehicle and install the two nuts using a 10 mm socket and ratchet. (Fig. U) Bolt the front tailpipe
hanger grommet assembly to the vehicle frame using the 10mm socket and ratchet. (Fig. V) Snug the 3” clamp
installed in step #6 using a 15mm deep socket and ratchet.
NOTE: The rear tailpipe hanger has plenty of adjustment. Ideally the bottom lip of the hanger grommet should be
parallel and level with the vehicle chassis. Loosening and adjusting the positon of the hanger grommet will result in
lateral and vertical tip adjustment.
7. Locate the stock passenger side tailpipe assembly. Slide the inlet end of the tailpipe into the expanded passenger
outlet. (Fig. W) Next, slide the rear tailpipe hanger grommet assembly against the vehicle frame, insert the
threaded stud assembly from the rear of the vehicle and install the two nuts using a 10mm socket and 3/8” ratchet.
(Fig. X) Bolt the front tailpipe hanger grommet assembly to the vehicle frame using a 10mm socket and ratchet.
(Fig. Y) Snug the 3” clamp installed in step #5 using a 15mm deep socket and ratchet.
NOTE: The rear tailpipe hanger has plenty of adjustment. Ideally the bottom lip of the hanger grommet should be
parallel and level with the vehicle chassis. Loosening and adjusting the positon of the hanger grommet will result in
lateral and vertical tip adjustment.
8. Visually inspect the exhaust system position, tip alignment, clamp orientation and position, and exhaust pipe
clearance. Make any necessary adjustments at the slip joints. Check clearances between the spare tire and rear
leaf spring suspension on both driver and passenger sides. (Fig. Z, AA, BB)
