Removal of Stock System:
1. Apply a penetrating lubricant liberally to all exhaust fasteners,
hangers and rubber insulators.
2. Loosen the band clamp behind the catalytic converter and
disconnect the factory exhaust system.
3. Remove the exhaust system from the rubber insulators and
remove from under the vehicle. If a hoist is not available for use,
it may be necessary to cut the tail pipe behind the muffler for
removal of the system.
Installation of MBRP Inc. Performance Exhaust:
1. Place the Adapter provided into the factory band clamp located
behind the catalytic converter. Install the Extension Pipe into
the Adapter placing the bend under and around the cross
member. Rotate the Extension Pipe to position the bend
towards the driveshaft. See Figure 1. The Extension Pipe does
not require cutting to fit crew cab trucks. For extended cab
trucks, approximately 9 ½” needs to be cut off the end with the
longest section of pipe. (Installation tip: Temporarily hang the
Muffler and the Tailpipe in place and measure to the Adapter
to verify the length required).
2. Position the Extension Pipe as shown and loosely install the
Hanger Clamp with the shortest hanger. See Figure 2. This will
support the Extension Pipe during the Muffler installation.
3. Crew cab & extended cab long box trucks require the use of the
18” Extension Pipe provided. This is to be positioned between
the Muffler and Extension Pipe. See Figure 3. The 18”
Extension Pipe is not required with short box trucks.
4. Install the Muffler onto the Extension Pipe. See Figure 4. See
Figure 5 for the proper direction of air flow through the Muffler.
