Regular Cab Models
1. Temporarily install the Passenger Side and Driver Side Over Axle Pipes by placing hangers into the factory rubber
insulators. Loosely install the Muffler onto the Over Axle Pipes with the Driver Side Over Axle Pipe connected to
the muffler outlet closest to the drive shaft. Support the Muffler so that it is level with the vehicle. Now measure from
the front of the Muffler to the “Y” pipe. This will give you the required length for the Extension Pipe. Remove the
Muffler and Over Axle Pipes.
2. Cut the Extension Pipe to the required length. Install the expanded end of the Extension Pipe over the factory
exhaust system behind the “Y” pipe. Now install the first Hanger Clamp onto the Extension Pipe to help support it.
3. Place the Muffler onto Extension Pipe.
4. Loosely connect the Driver Side Over Axle Pipe to the outlet closest to the drive shaft and place the hanger into the
rubber insulator.
5. Feed the Passenger Side Over Axle Pipe over the axle and connect it to the remaining muffler outlet. Now place the
hanger into the rubber insulator.
6. Feed the expanded end of the Driver Side Tail Pipe from the rear of the vehicle over the axle and connect it to the
Driver Side Over Axle Pipe.
7. Move the Driver Side Tail Pipe into approximate position. Using the factory hole provided in the frame located
directly above the tail pipe hanger, attach the Hanger Assembly provided using the supplied hardware.
8. Remove the factory rubber insulator for the factory tail pipe. Now feed the expanded end of the Passenger Side Tail
Pipe from the rear of the vehicle over the axle and loosely connect it to the Passenger Side Over Axle Pipe.
9. Move the Passenger Side Tail Pipe into approximate position. Using the factory hole provided in the frame located
directly above the tail pipe hanger, attach the Hanger Assembly provided using the supplied hardware.
10. Install the Mirror Polished Tips. It is recommended to install them at this point to assist with the final system
alignment.
11. Install the Hanger Clamp around the front muffler joint and into the factory rubber insulator located on the frame
near the front of the Muffler.
12. Install the provided Clamps to the pipe connections where required. Align the exhaust as required before tightening
Clamps.
13. Starting at the front of the exhaust, tighten all clamps and connections.
14. Check along the whole length of the exhaust system to ensure that there is adequate clearance around the spare tire,
fuel and brake lines or any wiring. If any interference is detected relocate or adjust.
