Vehicle Fitment:

- NOT designed for use with 2011-2014 GT Mustangs, see P/N: HPMR19.

Additional Notes:
- This after-cat H-Pipe is not intended to be used in conjunction with shorty, mid-length or long tube headers unless they specifically use the factory connection points.
- Replacement Band Clamps are NOT included as they will be reused from the stock H-Pipe.
- MRT does NOT recommend the use of an impact gun on the included hardware as overtightening can result in damage. The torque specifications for the included hardware is 22 ft/lbs.

Tech Tips:
- We strongly suggest applying penetrating spray lubricant to the factory exhaust system hardware prior to disassembly. In some cases, applying the day prior or multiple applications may be necessary to free up corroded components.
- Initial operation after installation will heat-cycle the tubing causing expansion and contraction. Because of this, MRT suggests that you check all clamps and re-tighten if necessary after approximately 30 miles of driving.
