Install your AWE tip outlet section (C17), onto
the AWE single exit tube (E30) as shown in
Figure 9.
Ensure the C17 is parallel with the body line of
the bumper.
The C17 tip merge is symmetrical so top
versus bottom orientation does not
matter.
Install your AWE single exit tube (E30), place a
clamp on the up turned end of the AWE
overaxle inlet tube (E26) shown at (A) in
Figure 8.
Bottom out the slip joint, then slide the hanger
bar into the factory hanger, as shown at (A) in
Figure 8.
STEPS 8-13 ARE FOR SINGLE EXIT SYSTEMS ONLY
To install the exhaust tips with integrated
clamps, first, attach the exhaust tip in the
proper orientation onto the exhaust outlet tube.
Insert one of the carriage bolts from the
hardware kit (3910-41010) through the tab on
the exhaust tip and thread on one of the
corresponding nuts.
Using anti-seize on the bolt threads will help
installation and prevent breakage of hardware.
This exhaust system only has 2 exhaust
tips while the integrated clamp kit has
enough hardware for our 4 tip exhaust systems.
You will have 2 sets of hardware left over that
will not be used.

Install the provided exhaust hanger split collar clamps. Use the included hex wrench to help keep the
exhaust system aligned and secure. Install these clamps on each hanger bar of the AWE overaxle
inlet tube (E26), as shown at (A) in Figure 12.
To install the exhaust tips, use the remaining
two 3” exhaust clamps and slide them onto the
tip merge before installing the exhaust tips.
Note: Exhaust tips should be installed
with the logo pointing up and the slash-
cut edge of the tip running parallel with
the edge of the bumper. Since the tip merge is
symmetrical, one tip will be seated slightly
deeper on the tip merge.

Go through and adjust the joints so the slip fit
joints are fully bottomed and there are no gaps.
Confirm there is no contact to any braces, heat
shielding or the chassis of the vehicle
When the exhaust is in the correct orientation,
tighten all exhaust clamps to a minimum of 60
ft-lbs and the installation is complete.
It is now recommended to drive the car to allow
the exhaust to heat cycle after all clamps and
tips are fully tightened.
At this point the exhaust will be very hot,
allow to cool before work continues.
Check the tips for correct alignment, adjust as
needed.
Don’t forget to look below for any
troubleshooting needs!

Before the rear axle tubes can be installed, the 2 new AWE hangers (E07) must be installed on the
driver side and passenger side frame rails.
Start by placing the hanger bracket (E07) on the frame rail. The driver side hanger (A), shown in
Figure 14-1 will face the cab, the passenger side hanger (B) shown in Figure 14-2 will face the rear
bumper.
Using the provided hardware, slide a washer onto the bolt, and slide the bolt through the hole on the
hanger (C). On the backside, place a nut on the bolt and tighten it fully.
Install your AWE overaxle tri-section (E27).
Slide a provided clamp over the slip joint, you
want to make sure the driver’s side leg (A) is
parallel with the bed of the truck, as shown in
Figure 15.

Install your AWE driver side tailpipe (E31).
Start by sliding a provided clamp over your
tailpipe and bottoming it out on the overaxle tri-
section (E27). Then slide the hanger bar into
the AWE rubber hanger on the AWE hanger
bracket (E07), as shown at (A) in Figure 16-1.
Next install your passenger side tailpipe (E32)

bottom it out on the overaxle tri-section (E27).
Then slide the hanger bar into the AWE rubber
hanger on the AWE hanger bracket (E07), as
shown in (B) Figure 16-2.
Note: While installing the AWE dual exit
system, the OE side exit exhaust hanger
will not be used. It can be removed while
installing the passenger side tailpipe (E32), so
it will not be in the way of the AWE system.
For the best tip fitment, align the Accu-seal
clamp to cover only the slot, shown by Arrow A
Torque the tip clamp to a minimum of 60 ft./lbs.
NOTES:
• It is required to apply anti-seize to the
threads to prevent thread binding,
shown by Arrow B
• It is okay to have the clamp extend
beyond the edge of the tip inlet.
