FOR CHEVY/GMC SMALL BLOCK 305-454 V8 BLACK STEEL HUGGER HEADER/EXHAUST MANIFOLD. 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 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. An added benefit is a more performance oriented exhaust sound. Made of High Quality Durable Mild Steel Material. TIG welded CNC Machine Flange.
