Removal:
1) Raise vehicle and support securely with stands. To ease the removal of the stock system,
spray a penetrating lubricant onto the rubber hangers.
2) Using a 13mm socket unbolt the left tailpipe assembly at the flanged connection at the rear of
the muffler. Slide the three hanger rods out of the rubber mounts on the vehicle and remove the left
tailpipe assembly
3) Then using a 13mm socket, unbolt the body brace between the catalytic converters and the
muffler assembly. (Save this brace and the four nuts for reinstallation after the Flowmaster system is
installed)
4) Support the right side muffler with a stand, then using a 15mm socket, loosen the clamps at
the slip fit connections behind the catalytic converters. Remove the three remaining hanger rods from
their rubber mounts on the vehicle and slide the system back off of the head pipes.
Installation:
1) Begin by placing a supplied clamp onto each of the slip fits of Scavenger pipe #16466S. Then
place the Scavenger pipe onto the back of the stock head pipes (make sure the Flowmaster
embossing is facing the ground). Level and center the assembly in the drive line tunnel and support
with a stand. Tighten the two clamps enough to hold but still allow for adjustment. Then reinstall the
body brace using the nuts removed in Step 3 (make sure there is clearance between the Scavenger
pipe and the cross-member).
2) Place a supplied clamp onto the inlet of each muffler #852546-Z. Then slide the mufflers onto
the back of the Scavenger pipe assembly. Level the mufflers and tighten the clamps enough to hold
but still allow for adjustment.
3) Place a supplied clamp onto the left muffler outlet, then place left tailpipe #16626S into position
and slide the hangers into the factory rubber mounts. Slide tailpipe into the muffler outlet. Rotate so
hangers are level and tighten clamp enough to hold but still allow for adjustment. Repeat this step for
right tailpipe #16627S.
4) Reinstall the body brace that was removed in step 3 using the original bolts.
