Suggested Tools for Installation:
❑ 3/8" ratchet and metric sockets ❑ Sawzall or Hacksaw
❑ Jack and jackstands ❑ Liquid penetrant and rubber lubricant
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. Using a sawzall or hacksaw, cut the factory I-pipe 6”
back from the front face of the 2-bolt flange.
4. Use penetrating oil on all hanger isolators.
5. Use a long pry bar to pull the rubber isolators 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. Using a 2-1/2” band clamp, install the new I-pipe
onto the pipe that was cut behind the OE 2-bolt
flange, engage hanger into rubber isolator. Only
snug the clamp at this time.
2. Slip the muffler onto the intermediate pipe with a
2-1/2” band clamp on the front. NOTE: Inlet end of
muffler is marked. Snug the clamp so you can adjust
the system later.
3. Place a 2-1/2” band clamp on the outlet of the
muffler.
4. Install the overaxle pipe and engage it into the stock
rubber hanger isolators. Snug the clamps.
5. Slip tailpipe onto overaxle pipe, install 3” band clamp
and snug clamp.
6. Check for clearance to body, frame, and driveline as
you tighten the system from front to rear.
7. Check for leaks and correct, if necessary.
WARNING!!!
Exhaust gas contains carbon monoxide, a deadly invisible gas.
Correct any leaks before driving!
IMPORTANT NOTE:
Proper installation is the responsibility of the installer. Improper installation will void warranty and may
result in poor performance and engine or vehicle damage.
