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 headers isn? T available due to steering and cross member clearance issues.
Tubing has been optimized for the 5.0L(305ci), 5.3L(327ci), 5.7L(350ci), and 6.6L(400ci) engines. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque.
