PARTS LIST (SWITCHPATH SYSTEMS)

Inspect ALL parts prior to disassembly of vehicle; If damaged or MISSING, please contact the place of purchase immediately.

Inspect ALL parts prior to disassembly of vehicle; If damaged or MISSING, please contact the place of purchase immediately.

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.

COMPLETE THIS PROCESS BEFORE MOVING FORWARD
Before starting installation, the factory exhaust valves must be in the open position. Bring the engine 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.

STEP 1
Begin by removing the OE bolts mounting the OE chassis brace to the body, as shown in Figure 1.
Note:
The OE hardware will be  reused with the install of your AWE exhaust.

STEP 2
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.

STEP 3
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.

STEP 4
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.

STEP 5

Before starting Step 5 ensure you have completed the process in the note before Step 1. Failure to do this can
cause misalignment in the valve motors Unplug the 2 OE valve motors (A).
Remove the bolts mounting the 4 hangers to the body (B), as shown in Figure 5.

STEP 6
Once the hangers are free, remove the OE exhaust system, as shown in Figure 6-1 and 6-2.
With your OE exhaust system removed, uninstall the OE valve motors as well as their respective springs and bolts from the factory brackets, mark the driver and passenger and set them aside. You will reuse them in later steps.

STEP 7
Deburr the edges of the OE exhaust tubes you just cut, as shown in Figure 7.

STEP 8
Begin installing your AWE system by, sliding your AWE X-pipe section (D89), with the supplied Accu-Seal clamps, over the cut section, as shown in Figure 8.
Note: The OE pipe clamp just before the cats can be loosened to help align the OE pipes and the AWE x-pipe.

STEP 9
It is crucial to install each section and exhaust band clamps correctly to prevent loose joints, exhaust leaks and rattles.
Arrow A shows the expanded pipe and the preinstalled exhaust clamp being brought up tothe corresponding pipe.
Arrow B shows the overlapping pipe installed correctly over the corresponding pipe.
Arrow C shows the exhaust band clamp being brought to the edge of the expanded pipe.

NOTES:

• Do not fully torque any exhaust clamp until the entire exhaust has been installed and adjusted.
• Torque specification is a minimum of 60 ft/lbs

STEP 10
Install your AWE driver side differential pipe (D90), with the supplied Accu-Seal clamp, as shown in Figure 10.

STEP 11
Install your AWE driver side differential pipe (D90) using the OE hanger removed earlier, as shown in Figure 11.

STEP 12
Install your AWE passenger differential pipe (D91), with the supplied Accu- Seal clamp (A), as shown in Figure 12.
NOTE: Reinstall the passenger side hanger (B) removed earlier.

With all AWE exhaust components installed, go ahead and torque down the clamps on the entire system, working from the front of the car to the exhaust tips.

TROUBLESHOOTING

adjusted exhaust.
This includes tip fitments and rattling due to chassis contact.

Wrong or missing parts| Double check the parts list for your system and compare them with what you received. Fill out our contact  form, found below and let us know what parts you need.

CARE

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.
