2007-13 Jeep Wrangler 2/4 Door HGC

Stainless Steel Cat-Back Exhaust System

PLEASE TRY TO INSTALL OUR WAY FIRST

1 Begin by placing the vehicle on a lift or 4 jack stands if needed so you can work safely under the vehicle.
2 Unbolt the factory muffler using the 15mm socket and remove the muffler from the vehicle. To aid in the

removal presoak the bolt and nut as well as the rubber bushings.

3 Next presoak and using the 15mm socket loosen the clamp at the end of the factory down pipe and re-

move the factory midpipe. 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 new tail pipe reusing

the factory mount locations and rubber hanger bushings.

5 Install the M-80 muffler using 2 of the HVC21 clamps. DO NOT TIGHTEN AT THIS TIME.
6 The mid-pipe is next. We left extra length on this pipe for your convenience. Carefully measure from the

end of the factory down pipe to the muffler adding enough to account for the mid-pipe slipping over the factory

down pipe and into the muffler so not to cause a leak. Four door owners only slight trimming may be needed.

Two door owners will cut significantly more off. Remember Measure three times and cut once.

7 Once you have trimmed or cut the midpipe to length install it along with the third HVC21 Clamp and the

HJJ010 hanger clamp. Note not all vehicles will use the HJJ010 hanger clamp. It is designed as extra support for

the midpipe and installs at the hanger location just behind the factory midpipe. If this clamp interferes with your

transfer case DO NOT USE THE Clamp.

8 Now that you have all the components loosely installed you can start making adjustments to align the

system. Once you are happy with the alignment tighten all the clamps. Air tools for this step are highly recom-

mended.

9 Lastly start your vehicle and check for leaks. It is not uncommon to see condensation coming from the

relief cuts in the pipe for the first few hundred miles. Double check all clamps for tightness after the first week of

driving.

Now it’s time to fire up that Wrangler and enjoy your

new Pypes Performance Exhaust.
