Installation Instructions
3/2/06
Installation:
1) On the inside of the rear frame rails, roughly 10” forward of the bumper, you will find holes that will be
used to mount the tailpipe hanger brackets. You should see a square hole with a round hole just below it.
Carefully place the 3/8” bolts through the square hole and back so that they stick out of the round hole.
Then place the hanger brackets #310HA(left) and #311HA(right) onto the bolts, and secure with nuts
and lock washers. Slide a rubber hanger #HA168 onto each of the hanger mounts.
2) On the right, rear section of the floor pan just ahead of the rear axle there is a factory hanger bracket spot
welded in place. Fasten the hanger mount #309HA to the inner side of the bracket with a 3/8” bolt
washer and nut. Slide a rubber hanger #HA168 onto the hanger mount. Slide clamp hanger #287HA
into bottom hole of the rubber hanger. The hanger rod should be inserted from the inside, out.
3) For the left side there are no factory locations for a hanger, so you will need to drill some holes. Take
the hanger mount #308HA and try to mirror the location of the right hanger as close as you can. Mark
the two hole locations and drill the pan with a 3/8” bit. Now you must go inside the vehicle and remove
the rear seat so that you can see the holes you drilled. Place the mounting plate #244HA through the
holes, and replace the seat. Now go back and fasten the hanger mount in place with 3/8” nuts and
washers. Slide a rubber hanger #HA168 onto the hanger mount. Slide clamp hanger #288HA into
bottom hole of the rubber hanger. The hanger rod should be inserted from the inside, out
4) Place the mufflers up into position and support with stands, then place the outlets of the mufflers into the
clamp hangers and tighten just enough to hold in place.
5) Slide a 3” clamp #MC300R over each muffler inlet, then place H-pipe assembly #26168 in its
approximate position underneath the vehicle and connect the back of H-Pipes into the muffler inlets and
support with a stand. Tighten clamps just enough to hold but loose enough to allow for adjustment.
6) Place both tailpipes #26170 and #26171 up over the rear axle, and into the outlets of the mufflers. Slip
the hanger rods at the rear of the pipes into the rubber hangers that were installed in step 1.
7) The front connector pipes #26172 and #26173 are long enough to allow for many different header
combinations therefore, it is necessary to determine the proper length of the connector pipes. Once the
proper length is determined, trim the front connector pipes to fit.

8) Once the connector pipes are cut to proper length, raise them into position and connect them to the H-
Pipe and header collectors or manifold down pipes using a standard header flange, Flowmaster venturi
cone, or Flowmaster Ball Flange kit.
9) Make any final adjustment to the position of the mufflers and pipes. Allow a minimum of ¾”clearance
around all parts. Then tighten down all clamps securely and install the 7/16” push-on hanger keepers
on the round stock sticking through the rubber muffler hangers. Be sure to allow adequate clearance for
full suspension travel and vibration.
NOTE: WE HIGHLY RECOMMEND WELDING ALL SLIP-FIT CONNECTIONS.
