DNA Motoring HDS-F15004-4WD+Y Stainless Steel Exhaust Header [04-10 Ford F-150]

High performance stainless steel header exhaust: 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

High performance stainless steel header exhaust: 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 back pressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.
