Description

Part #: 1521

BBK High Flow performance H pipes are designed to maximize the horsepower and torque of your 1986-1993 Ford Mustang 5.0 V8. Every BBK Performance H pipe is designed as a direct replacement for the factory pipe and features larger diameter 16 gauge 2-1/2 in. CNC mandrel bent aluminized steel tubing (with H crossover) and high flow catalytic converters to help increase exhaust flow and maximize performance to the rear wheels.
