J2 FOR 84-91 CHEVY/GMC 5.0/5.7 SBC SMALL BLOCK LONG TUBE EXHAUST HEADER 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 T-304 Stainless Steel with Computerized Mandrel-Bends for Strength and Durability.
