Our 4-1 Shorty Style off-road headers are designed to allow the exhaust gasses to flow more freely from each 4 cylinder bank and combine in a more efficient manner. Tubing has been optimized for the 4.8L and 5.3L 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. High Performance Stainless Steel Header Exhaust. Made of High Quality T304 Stainless Steel Material. TIG Welded CNC Machine Flange.
