Removal:
1) Begin by applying a lubricant of some type to the six rubber hanger rods/mounts that support the
mufflers. This will make the removal and installation much easier.
2) Locate the two hanger rods on the mid pipes that are near the rear end housing. Measure from the
end of the hanger rods, forward 9” and mark the mid pipes. Using a hacksaw or sawsall, cut both mid pipes.
3) Support the front of the muffler, and then completely remove the rubber hanger mount in front of the
muffler (keep for reinstallation). Now allow the front of the muffler to drop down, and slide the muffler forward
to disengage it from the rear rubber mounts. Once it is free it can be removed from under the vehicle.
Repeat the same procedure for the other side.
Installation:
1) We have experienced some variation in the heights of the factory mid pipes where they get cut. The
y
optimally should be the same height for proper fit of the new mufflers, so it’s recommended that you do
some checking with a tape measure. If they are different, you can use some muscle to “tweak” them (push
one side up and the other side down) to where they match. You will also want to use a die grinder or file to
deburr the sharp edges from the mid pipes where they were cut.
2) Place one of the supplied band clamps onto the inlet pipe of the right muffler. Place the muffler up
into position and slip the two rear hanger rods into the holes in the rubber mount. Swing the inlet neck up
and onto the factory mid pipe where you cut it. Now reinstall the rubber mount in front of the muffler. Repeat
the procedure for the left muffler.
3) Adjust the position of the mufflers to provide a satisfactory fit. A minimum of ½ clearance around all
parts of the system must be maintained; while keeping suspension travel and vibration in mind. Afte
r
adjustments have been made, securely tighten the inlet clamps. Slide the supplied hanger keepers onto the
ends of the hanger rods to prevent them from slipping out of the rubber mounts.
4) Finally, the stainless tips can be placed onto the muffler outlets. It is recommended that this be done
on the ground so that you can get a good view as to their proper positioning such as rotation and stick out.
Once properly aligned, securely tighten the pinch bolts to hold them in place. Note: If the vehicle is fitted with
an optional Ground Effects Package, you will need to trim 2.75” off the muffler outlets prior to installing the
tips.
