NOTE: Always refer to the manufacturer’s service manual for precise torque specifications
on all OEM fasteners.
CAUTION: The exhaust may be VERY HOT — allow adequate time for the system to cool
down before disassembly. Severe burns and injury will occur if skin comes into contact with
a hot exhaust system.
On the driver side catalytic converter measure
4.50” inches from the weld seam (A) towards
the rear of the vehicle.
Mark with tape (B) and an arrow pointing to the
rear of the vehicle, as shown in Figure 2.
It is extremely important that these
measurements are accurate as it will
effect fitment.
Begin by removing the OE bolts mounting the
OE chassis brace to the body, as shown in Fig-
ure 1.
Note: The OE hardware will be reused with the
install of your AWE exhaust.
COMPLETE THIS PROCESS BEFORE MOVING FORWARD
Before starting installation, the factory exhaust valves must be in the open position. Bring the en-
gine up to full operating temperature. With the engine running, press the Engine Dynamics button
to switch into Sport-Plus mode. Blip the throttle to audibly confirm the valves are open. If in doubt
of valve position, peer into the exhaust tips with a flashlight to confirm that they are open. While still
in Sport-Plus mode, shut off engine Disconnect the connectors from both valve electrical motors.
Allow exhaust to cool before proceeding with next install steps. Failure to follow this procedure
will result in the factory valve motors not aligning with the AWE Tuning exhaust valves.

Make a cut on the driver and passenger side exhaust tube along the rear edge of the tape, as
shown in Figure 4-1 and Figure 4-2.
NOTE: It is crucial that these cuts are accurate. Incorrect cuts will effect fitment.
Make sure that the cuts are perpendicular to the tube you are cutting.
On the passenger side catalytic converter
measure 7.00” inches from the weld seam (A)
towards the rear of the vehicle.
Mark with tape (B) and an arrow pointing to
rear of the vehicle, as shown in Figure 3.
It is extremely important that these
measurements are accurate as it will
effect fitment.

Once installed properly, your AWE exhaust will provide years of trouble-free performance.
The exhaust volume and sound will settle with usage; 800-1000 miles is required to break-in new
exhaust systems.
Also, please note that the rear 180Technology® resonator has a small drain hole to allow
condensation to escape. Water drops from this area are normal.
Periodic cleaning of exhaust tips is necessary to maintain proper finish, especially in areas prone to
road salt and caustic deicing solutions. Use a mild soap and water solution or car wax to clean the
finish. Avoid using abrasive polishes, as they can scratch the finish.
