Installation of MBRP Performance Exhaust

1. Determine the appropriate length of the extension pipe based on your vehicle’s wheelbase. Refer to Figure 3.
2. Loosely install the Front Pipe using the supplied hardware. Refer to Figure 4.
3. Install the appropriate length Extension Pipe onto the Front Pipe using a 3” Clamp. Refer to Figure 5.
4. Install the Hang Tight™ Hanger onto a 3.0” Band Clamp using the procedure shown below. (Hang Tight™ Hanger not exactly as shown)
5. Install the Hang Tight™ Hanger Clamp Assembly onto the Extension Pipe and into the factory isolator. Refer to Figure 6.
6. Install the Muffler onto the Extension Pipe and lightly secure with the Hanger Clamp. Muffler outlets will be at a 45º angle viewed from the rear, with the passenger-side outlet at the bottom. Refer to Figure 7.
7. Place a 2.5” Clamp over each Muffler outlet and insert the Driver-Side Over-Axle Pipe into the left upper Muffler outlet and factory isolator. Refer to Figure 8.
8. Install the Passenger-Side Over-Axle Pipe into the lower right Muffler outlet. Snug but do not completely tighten the 2.5” Clamp. Refer to Figure 9.
9. Install the Passenger-Side Tail Pipe onto the Passenger-Side Over-Axle Pipe and into the factory isolator. Refer to Figure 10.
10. Install the Hanger Assembly using the supplied Hardware through the lower of the pair of large holes in the driver-side frame. Tighten the hardware enough to support the pipe but leave the final tightening until the final step. The Hanger Assembly attachment allows for some height adjustment to align the Tail Pipes. Refer to Figures 11 and 12.
11. Install the Driver-Side Tail Pipe into the Hanger Assembly and onto the Driver-Side Over-Axle Pipe using a 2.5” Clamp. Refer to Figure 13.
12. Install the Exhaust Tips and adjust to your liking. Refer to Figure 14 and 15.
13. Tighten all hardware and clamps, starting at the front and working rearward to secure the system. Check along the full length of the exhaust system to ensure there is adequate clearance for fuel lines, vent lines, brake lines, frame, bodywork, suspension, and any wiring, etc. If there is any interference detected, relocate, or adjust to provide adequate clearance. Ensure all clamp connections are secure and components are unable to rotate or slide. Band clamps require approximately 45 lb-ft (60 N-m) of torque. Verify clearances, system security and band clamp torque after 30-60 miles (50-100 km) of driving.

Congratulations! You are ready to begin experiencing the improved power, sound and driving experience of your MBRP performance exhaust system. We know you will enjoy your purchase.
