tory mid-pipe. Save all the rubber hanger bushings as they will be reused.
4 Now it is time to start installing your new cat back system. Begin by installing the MJJ19 mid-pipe using 1
of the HVC21 clamps and the HJJ010 hanger clamp. Note not all vehicles will use the HJJ010 hanger clamp. It is
designed as extra support for the mid-pipe and installs at the hanger location just behind the factory mid-pipe. If
this clamp interferes with your transfer case DO NOT USE THE Clamp.

7 Now that you have all the components loosely installed you can start making adjustments to align the
system and tips. Once you are happy with the alignment tighten all the clamps. Air tools for this step are highly
recommended.
