TUBULAR RACING EXHAUST MANIFOLDS HEADER 04-10 FORD F-150/F150 XLT/FX4 5.4L V8

 

ITEM SKU: KOS-HDS-F150-04-54L-LONG

 

The exhaust manifolds found in the 2004-2008 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 in a more efficient manner. 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.
