• 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.
• that you have read and understand these instructions.


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 H-Pipe




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.

3. Remove the OEM over axle pipes by lowering the inlet ends and pulling them out towards the front of the car.

4. Remove both M10 bolts that secure the Panhard Bar Brace to the Driver Side Frame rail. Pull the brace downward to allow more room to remove the OEM mufflers. Slide the rubber isolator off the rearmost muffler hangers, then slide the muffler assemblies forward to remove them from the car.

Refer to Figure 3.

2. Install your S7228 Header Kit as per the instructions included in the kit.

Installation of MBRP Inc. Performance Exhaust:





1. Assemble the Driver side H Pipe and the Passenger side H Pipe on the floor. Be sure the expanded portion of the 2.25” Crossover Pipe is on the driver side of the car and that the appropriate clamps have been loosely installed. Refer to Figure 4.

2. Install a 3” Clamp over the outlet of each MBRP Header.

Refer to Figure 5.

3. Install the H pipe assembly onto the car by sliding the H pipe onto the header collectors.

Refer to Figure 6.

4. Remove the rear O2 sensors from the OEM Cats and reinstall them in the MBRP H pipe.

Refer to Figure 7.

5. Connect the O2 sensors to the factory wiring harness with the supplied O2 Sensor Extensions.

Refer to Figure 8.

6. Install your MBRP Cat Back Exhaust Kit as show in the Instruction Sheet supplied in the kit, or reinstall your OEM Exhaust.

7. Adjust the system to provide clearance between all other under body components and hoses. Tighten all clamps once properly adjusted.
