Owners manual
4) Adjust and level the X-Pipe and muffler assemblies to provide a satisfactory fit. A minimum of
1/2” clearance around all parts of the system must be maintained; while keeping suspension travel
and vibration in mind. After adjustments have been made, you may now securely tighten the
clamped connections.
5) For a more secure installation, we highly recommend placing a minimum 1” weld on either side
of the inlet slip-fit connections.
The following instructions will describe the steps required to install X-Pipe assembly #81107
with a Flowmaster Axle-back system.
Removal:
07/21/15
1) Raise the vehicle up on a hoist or rack to working height. If you don’t have access to a hoist or
rack, raise the vehicle and support securely with jack stands. To ease the removal of the stock
system, spray a penetrating lubricant onto the bolts of the two clamp connections just forward of the
center resonator as well as the rubber hangers just behind the rear differential and at the rear of the
vehicle.
2) Place a stand under the center resonator just forward of
the axle-back muffler assemblies. Loosen the clamps at the inlets
of the Flowmaster axle-back mufflers.
3) Using a 13mm wrench, loosen the two hangers just behind the rear differential from the cross
member and the two hanger mounts at the rear of the vehicle from the frame. Slide the muffler
assemblies toward the rear of the vehicle to disengage them from the factory system. Leave them
hanging in place for re-assembly onto the Flowmaster X-pipe assembly.
