Our 4-1 Block Hugger off-road headers are designed to allow the exhaust gasses to flow more freely from each cylinder bank and combine in a more efficient manner. Block Hugger style headers are meant to be used where space for long tube headers isnt available due to steering and cross member clearance issues. Tubing has been optimized for the 425, 472 and 500 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. 100% Brand New Professional Installation is Highly Recommended Installation Instruction is NOT Included.
