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 + Y-Pipe Exhaust System.
