Removal of Stock System:
1. Scribe a line 12” from the front face of the stock muffler. (See Fig. A)
2. Place a chain style cutter around the exhaust pipe at the scribe line
location and cut the exhaust pipe. (See Fig. B)
3. Use a 13mm socket to loosen the spherical clamp and remove the
factory headpipe. (See Fig. C)
4. Remove the grommets from the tailpipe hangers at the muffler exit, the
spare tire and finally ahead of the muffler, using grommet pullers or
similar device. (See Fig’s D, E & F)
Note: Using a soapy solution on the grommet hole will make the job
easier.
5. Remove the muffler and rear tailpipe section from the vehicle by lifting
the tailpipe over the rear axle and forwards toward the front of the
vehicle. (See Fig’s G & H)
This completes the removal of the stock system.
