Package Includes:
1 x Set of Exhaust HeadersHardware as Shown in the Picture Above
The exhaust manifolds found on the 1967-1975 Ford Big Block FE engines were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-1 Shorty Style off-road racing headers are designed to allow the exhaust gasses to flow more freely from each cylinder and combine in a more efficient manner. Tubing has been optimized for the 5.4L(332ci), 5.8L(352ci), 5.9L(361ci), 6.4L(390ci), 6.6L(406ci) and 7.0L(427ci) engines. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.
