These instructions cover the following systems: S5000304, S5000409 S5000AL
Removal of stock system:
1. Apply a penetrating lubricant liberally to all exhaust fasteners, hangers and rubber insulators.
2. Remove the nuts from the studs holding the front flange together and disconnect exhaust system.
3. Remove the hangers from the rubber insulators and remove the exhaust from the vehicle. If a hoist or
hydraulic lift is not being used the tail pipe may need to be cut to clear the rear axle.
4. The studs located in the exhaust flange must be removed. This can be accomplished using a hammer.
The studs will be replaced by hardware supplied with the system.
Installation of MBRP Inc. Performance Exhaust:
1. Loosely attach the extension pipe at the flange using the hardware provided and slide hanger into rubber
insulator located on the frame.
2. Install muffler onto the mid pipe and install the hanger into the factory rubber insulator located above the
rear of the muffler.
3. Feed the tail pipe over the axle and loosely attach it to the muffler. Install the tail pipe hanger into the
factory rubber insulator located directly above the hanger.
4. Install the mirror polished tip. It is recommended to install them at this point to assist with the final system
alignment.
5. Install provided clamps to the pipe connections where required. Align the exhaust as required before
tightening clamps.
6. Starting at the front of the exhaust tighten all clamps and connections.
7. 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.
Congratulations! You are ready to begin enjoying the improved performance and driving experience of your
