Hardware Kit:

STEP 1

Installation of the AWE Performance Exhaust System is the reverse of the removal OEM exhaust.
Always refer to the manufacturer service manual for L_’ precise torque specifications on all OEM fasteners.
Before removing the factory exhaust, soak the fasteners that hold the exhaust in place with a penetrating oil.
Start by removing the two (2) 12mm nuts at the exhaust flange behind the catalytic converter, as shown by the arrows in Figure 1. These are best accessed under the hood from the driver side, reaching across the backside of the engine; the third bolt is accessed under the car.

STEP 2

The remainder of the removal process takes place under the car. Removing the belly pan is accomplished by removing the fasteners as shown by the arrows in Figure 2.
One (1) T25 Torx, at Arrow A in Figure 2.
Two (2) quick release fasteners, at Arrows B in Figure 2.
Five (5) quarter-turn fasteners, at Arrows C in Figure 2.

NOTE : Before removing any braces or hanger supports, be sure the exhaust is supported either by a second set of hands or support stands.
Remove the four (4) 10mm triple square bolts that secure the cross brace in place, as shown by the arrows in Figure 3.
The middle muffler hanger bracket is also held into place through these bolts; once removed, set aside the hanger and bracket for reuse on the AWE SwitchPath™ Exhaust mid pipe section (part VN) STEP 4

Starting from the rear of the car, support the OEM rear mufflers and loosen the two (2) 13mm bolts that secure thesleeve clamps, as shown by the arrow in Figure 4.
Remove the OEM rear muffler section from the car. STEP5

Loosen and remove the last remaining 12mm nut from the exhaust flange at the catalytic converter, as shown by Arrow A in Figure 5.
Loosen and remove the 13mm bolt that secures the downpipe to the support bracket, as shown by Arrow B in Figure 5. STEP6

Properly support the OEM mid muffler and downpipe before complete removal.
Remove the two (2) 10mm triple square bolts that hold the hanger bracket onto the cross brace; shown by the arrows inFigure 6.
The OEM exhaust can now be completely removed from thecar allowing the AWE SwitchPath™ exhaust to be installed inthe reverse order of removal.
Transfer the OEM hanger bushings and brackets onto the corresponding AWE exhaust parts. STEP7

Starting at the downpipe upper section (part VL), reuse the factory mounting hardware and gasket for the exhaust flange.
Reinstall the mounting bracket and hanger hardware, as shown by the arrow in Figure 7.
Reinstall and torque the flange nuts to manufacturer specification along with the spring-bolt into the support bracket. Be careful; do not overtighten the spring-bolt.
NOTE : Spraying an assembly lube into the hanger bushings will make installation easier. STEP8

Slipping a 3.0” Accu-Seal clamp over the inlet side of the downpipe lower section (part VM), install into place as shown in Figure 8. Be sure to fully seat the pipe over the corresponding pipe.
Do not torque any of the clamps into place until the entire system has been installed and adjusted. STEP9

Use a 3.0” Accu-Seal clamp over the inlet portion of the midpipe section (part VN) and install into place, as shown by Arrow A in Figure 9.
Transfer the OEM hanger bushing assembly into location and reinstall the cross brace, as shown by Arrow B in Figure 9. STEP10

Place a 3.0” Accu-Seal clamp over the inlet of the driver rear section (part VQ) and install onto the mid-pipe section, as shown by Arrow A in Figure 10. Install the hanger into the bushing located at the driver side rear corner of the car.
Place a 2.5” Accu-Seal clamp over the inlet of the passenger rear section (part VR) and install onto the “T-section” of the driver rear section, as shown by Arrow B in Figure 10. Insert the hanger on the rear muffler into the bushing located at the passenger rear corner of the car.

STEP11

It is crucial to install each section and Accu-Seal clamp correctly to prevent loose joints and exhaust leaks between the tubing connections.
Arrow A in Figure 11 shows the expanded pipe and the preinstalled Accu-Seal clamp being brought up to the corresponding pipe.
Arrow B in Figure 11 shows the overlapping pipe installed correctly over the corresponding pipe.
Arrow C in Figure 11 shows the Accu-Seal clamp being brought to the edge of the expanded pipe.
NOTES :

Do not torque any Accu-Seal clamp until the entireexhaust has been installed and adjusted.
Torque specification is a minimum of 40 ft/lbs.

STEP12

To accomplish the best tip fitment, align the 2.25” tip clamp to cover only the slot, as shown by Arrow A in Figure 12.
The clamp should only be covering the section of the tip that has been slotted, as shown by Arrow B in Figure 12.
Torque the tip clamp to a minimum of 11 ft./lbs.
NOTE : It is recommended to apply anti-seize to the threads to prevent thread binding, shown by Arrow C in Figure 12. Additionally, it is okay to have the clamp extend beyond the edge of the tip inlet. STEP13

Using the remaining 2.5” tip clamps, install the 102mm slash cut tips into location. The AWE logo is offset so the angle of the tip can match the angle of the cutout in the bumper. This means that the tips are specific to driver and passenger sides.
Once the exhaust tips are properly aligned, starting at the downpipe section moving towards the rear of the car, torque each Accu-Seal clamp to 40ft/lbs. STEP14

AWE SwitchPath™ Remote kit installation instructions:
NOTE : Disconnect the battery before performing any electrical work.
Located in the trunk, open the access panel that contains a vehicle control unit on the left hand side of the car, as shown in Figure 14.

STEP15
The SwitchPath™ Remote installation kit includes a control box and harness. The red wire is used in conjunction with the blue Posi-Tap connector, as shown by Arrow A in Figure 15. Tap into a wire that is a “switched” 12-volt circuit.
Using a 10mm socket, loosen and remove the nut shown by Arrow B in Figure 15. Lift the control unit off the mount and install the ground wire.
Reinstall the vehicle control unit.

STEP16

Located next to the box location is a grommet that is directlyover the valve motor on the SwitchPath™ Exhaust system.
Shown by the arrow in Figure 16, slide the male connector from the SwitchPath™ control harness through the opening, then reinstall the grommet.

STEP17

Use the supplied Zip-Ties to neatly place the remainder of the SwitchPath™ control box and harness inside the cavity, as shown in Figure 17.

STEP18
From under the car, the male connector should be coming out of the grommet located by Arrow A in Figure 18.
Plug the male connector into the female connector on the valve motor, shown by Arrow B in Figure 18.
Reconnect the battery.
Without starting the vehicle, turn on the vehicle to check operation of the valve, cycling it open and closed with the included remotes to insure proper operation. STEP19

The SwitchPath™ Remote can be hung on a keychain, or located on the inside the vehicle using the supplied mount.
Use the supplied double-sided tape or plastic screws to secure the mount to the desired location within the cabin (i.e. in the center console or glovebox).
Mount shown next to the remote in Figure 19.

TROUBLESHOOTING

Issue	Solution
Exhaust is not fitting correctly	Most fitment issues are due to improperly

adjusted exhaust. This includes tip fitments and rattling due to chassis contact. Check out our fitment guide for more installation tips.
Incorrect 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.
