DISASSEMBLY
1. Raise vehicle and support with proper jackstands for
the weight, leaving the suspension hanging.
2. Use caution around hot exhaust systems to avoid
burns.
3. Use penetrating oil on all nuts and bolts.
4. Remove the bolts and clamps from the system and
lubricate the rubber hangers.
5. Use a long pry bar to pull the rubber hangers off of the
pipe hangers.
6. Remove the old system. In some cases, you will find it
easier to cut the overaxle pipe to remove it.
ASSEMBLY
1. Bolt I-pipe to factory outlet flange (behind catalytic
converters).
Note: Do not tighten flange bolts at
this time (snug only).
2. Slip the muffler onto the intermediate pipe with a
3-1/2” band clamp on the front.
Note: Inlet end of
muffler is marked. Snug the clamp so you can adjust
the system later.
3. Install a 3 1/2”band clamp on the front of the overaxle
pipe and engage it into the stock rubber hangers as you
slip it into the muffler. Snug the clamps.
4. Slip tailpipe onto overaxle pipe, install 3” band clamp
and snug clamp.
5. Install hanger clamp assembly #23-4039 onto I-pipe
and engage into stock rubber hanger. Snug clamp to
pipe.
6. Working from the front of the system, align and tighten
each pipe from the cat back.
7. Check for clearance to body, frame, and driveline as
you tighten the system from front to rear.
8. Check for leaks and correct, if necessary.
WARNING!!!
Exhaust gas contains carbon monoxide, a deadly invisible gas. Correct any leaks before driving!
