Precision machined steel flanges that provide a tight seal at the head and allows a high flow rate through the primary tubes. Made From High Quality T304 Stainless Steel For Strength & Durability.
Constructed With TIG Welded CNC Machine Flange For Precision & Fitment. 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 5.2L(318ci) and 5.9L(360ci) 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.
