- that ALL components shown above are present.
- that ALL mating components fit together.
- that there are no damaged components
- that the system you have purchased is appropriate for your vehicle year, model and configuration.
- that the system will not interfere with any modifications previously installed or planned.

If you have any questions or are uncertain about any aspect of the installation of this system to your vehicle please contact your dealer before commencing installation.

Removal of Stock System:

1. Apply a penetrating lubricant liberally to all exhaust fasteners, hangers and rubber insulators.

2. Loosen both OEM clamps located at each muffler inlet, and both OEM band clamps at the H Pipe outlet. Lift the lock tab to slide the band clamp rearward. Do not discard these clamps. Refer to Figures 1 and 2.
