MBRP S6114 - Manual (Page 2)

Removal of stock system:
1. Apply a penetrating lubricant liberally to all exhaust fasteners, hangers and rubber insulators.
2. Remove the exhaust system from the rubber insulators and remove all of the clamps from the system.
3. Separate the slip joint behind the muffler and remove the tail pipe. Next, separate the slip joint connecting the
down pipe and the extension pipe to remove the muffler and extension pipe. Now loosen the band clamp
connecting the down pipe to the turbo and remove the down pipe. Do not discard the band clamp as it is
required for the installation.
4. 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 by sliding the hanger into the OEM hanger
bracket and then attaching the flared end to the turbo using the stock band clamp. Do not fully tighten until all
components are in place.
2. Install the 4" to 5” Extension Pipe over the Down Pipe. The 4” to 5” Extension Pipe provides the required
length to fit a Quad Cab Long Bed truck. The 4” to 5” Extension Pipe 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 Extension Pipe or Mid 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 on the frame
near the inlet of the Muffler.
5. Remove the factory rubber insulator for the factory tail pipe and install it onto the
Tail Pipe hanger. Install the Tail Pipe from the rear of the truck, over the axle and
attach to the outlet of the Muffler. 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.
