Instruction Manual
1. Begin by placing the vehicle on a lift or four jack stands at maximum height. This will aid in an easier installation.
2. Unbolt the factory band clamps (13mm wrench) connecting your factory axle-back to your mid-pipes also loosen the
two butt clamps (15mm socket) that connect your midpipes to the H of X-pipe. Soaking your factory rubber mounting points
with penetrating oil to allow for easier removal. Next, remove both factory mufers from under the car.
3. In this kit it’s is necessary to reuse the factory clamps that are attached to the
axle back. Remove them by cutting the tab that connects the clamp to the factory mufer.
Trim the tabs as close to the clamp as possible. Make sure to remove all burs from the
clamps.
4. To aid in the installation of your new Pype Bomb Axleback remove the factory ex
-
haust hanging brackets closest to the front of the car from the framerail (13mm wrench or
socket). Preinstall them on the axleback wire forms keeping the same orientation as they
where on the framrail. Now you can install you axleback starting with the 13mm bolts that
hold the hanger bracket to the frame making sure that the locating pin is in it proper hole.
Next install rear most rubber hanger to the wire form.
5. At this point you can attach the Axle Back to the factory mid-pipe using the re
-
cycled clamps. Just get the clamps snug at this point so proper alignment can be per
-
formed. Remember this is a ball socket style connection that allows for some misalign
-
ment without compromising seal.
6. Once you are happy with the alignment of the Axleback you can nish tightening
the clamps. We recommend the use of air tools for this step.
Note: If you nd the new tips are not aligned properly in the bumper cutouts, you may need to adjust your factory mid-
pipes by loosening the two band clamps located where your factory h-pipe meets the mid-pipes. A slight rotation of the mid
pipes will allow for the best t.
7. Be sure to check all the connection points periodically, as they may come loose.
Now it’s time to re up that muscle car and enjoy your
new Pypes Performance Exhaust.
