Aggressive Muscle Car Rumble. This free flowing shorty MAC off-road mid-pipe not only increases the horsepower and torque of your Mustang, but with its unique Pro Chamber cross over design it adds a more aggressive muscle car rumble to the sound of your exhaust, that the standard H-pipe just can't match.
