Factory Exhaust System Removal:
1. Remove both sets of hardware that secure the Cat-Back to downpipe flange connection on the factory center
pipe using a 14mm socket and a 12mm wrench. (Fig A)
2. Place a support under the front of the system to ensure it doesn’t fall during removal. Using grommet pullers or
similar device, remove the front hanger grommet from the axle pipe. (Fig B)
NOTE: The use of a soap and water solution may aid in the removal of hanger grommets.
3. Remove both hanger grommets from the rear muffler on the driver’s side using grommet pullers or similar
device. (Fig C & D) Repeat on passenger side.
4. Carefully remove the factory exhaust by moving it down and towards the rear of the vehicle. The exhaust can be
removed as a single unit. (Fig E)
5. Remove the donut gasket at the flange on the factory downpipe. (Fig F) It may be helpful to use a small
flathead screwdriver to free the donut gasket from the lip on the downpipe. The donut gasket will not be
reused. This completes the removal process.
