1999-2003 Ford F-150 5.4L V8 Long Tube Headers - Stainless Steel w/ O2 Bungs & EGR Port - Performance Exhaust Upgrade
ℹ️ DESCRIPTION
The exhaust manifolds found in the 1999-2003 Ford F150 and F250 were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-1 Long Tube off-road headers are designed to allow the exhaust gasses to flow more freely from each 4 cylinder bank and combine more efficiently. Tubing has been optimized for the 5.4L(330ci) engine. 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.
