MBRP S6112 - Manual (Page 2)

Removal of stock system:
1. Separate the stock exhaust at the slip joint by the muffler. Remove the rear exhaust from the rubber hangers and
remove the system from under the truck.
2.
Using a 15mm socket or wrench, remove the two (2) bolts at the turbo flange and remove the stock down pipe.
3.
Remove the spare tire. You may not be able to reinstall your spare tire after the installation of this exhaust
system.
Installation of MBRP Inc. Performance Exhaust:
1. Install the Down Pipe in the same position as the stock down pipe and attach the flared end to the turbo using
the supplied hardware. Do not fully tighten until all components are in place.
2. Install the 4" to 5” Extension Pipe (46.75”) over the Down Pipe. Install the 34” Extension Pipe onto the 4” to
5” Extension Pipe. The combination of these two Extension Pipes provides the required length to fit a Quad
Cab Long Bed truck. These pipes will have to be cut to fit all other vehicles. Installation Tip: Temporarily install
the Muffler and Tail Pipe using the factory rubber insulators and the Hanger Clamp. Measure from the Muffler
to the 4-5”Extension Pipe to determine the length required. Cut the pipe to the required length.
3.
Install the Muffler over the required pipe so that the exhaust will flow
smoothly over the louvers. Refer to the illustration on the left.
4. Install the Hanger Clamp into the two OEM rubber hangers located
above the outlet of the Muffler.
5.
Remove the factory rubber insulator for the factory tail pipe. Install the Tail
Pipe from the rear of the truck, over the axle and attach to the outlet of the Muffler.
Move the Tail Pipe into approximate position. Using the factory hole provided in the
frame directly above the tail pipe hanger, attach the hanger provided (HG002) using
the supplied hardware. Finish hanging the Tail Pipe.
6.
Install the Hanger Clamp into the two OEM rubber hangers located above the outlet of the Muffler.
7. Install the provided clamps around pipes where needed. Adjust the Tail Pipe and check along the whole length
of exhaust system to ensure there is adequate clearance around the fuel and brake lines or any wiring. If any
interference is relocate or adjust.
8.
Make sure exhaust is in place before tightening clamps. Start at the front of the exhaust system and begin
tightening all connections.
9.
If a tip has been purchased, install and adjust to suit. Using a 17mm wrench tighten lock bolt located on Tip. The
Tip is not included with this kit. Tips may be purchased separately, check with your dealer.
Congratulations! You are ready to begin enjoying the improved performance and driving experience of your MBRP
Inc. performance exhaust system. We hope you enjoy your purchase.
