How to Install MBRP Installer Series H-Pipe - 3 in. to 3 in. on your Mustang

Installation Time

2 hours


Removal of Stock H-Pipe



1. It is not necessary to completely remove the cat back portion of the exhaust to install this product. Loosen the OEM Band Clamps at the H pipe outlets. Lift the lock tab and slide the extension pipes rearward to disconnect from the OEM H pipe.
2. Loosen the OEM ball joint clamp located after the cats and remove the H pipe from the car.
Refer to Figure 1.
3. Cut the retaining band that holds the clamp to the OEM H pipe. This clamp will be reused.
Refer to Figure 2.

Installation of MBRP Inc. Performance Exhaust:


1. Reinstall the OEM band clamps over the outlets of each OEM cat pipe.
2. 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 3.



3. Install the H pipe assembly onto the car by aligning the ball joint connections and then sliding the OEM band clamps over the connection.
Tighten the clamps just enough to hold the H pipe assembly in place but still allowing for adjustment.
Refer to Figures 4 and 5.

4. Install your MBRP Cat Back Exhaust Kit as show in the Instruction Sheet supplied with the kit, or reinstall your OEM Exhaust.
5. Adjust the system to provide clearance between all other under body components and hoses while ensuring the Tips are centered in the rear Fascia. Tighten all clamps once properly adjusted.


Congratulations! You are ready to begin experiencing the improved power, sound and driving excitement of your MBRP Inc. performance exhaust system. We know you will enjoy your purchase.
