Product Description: 05-10 Ford Mustang 4.6L V8
The exhaust manifolds found in the 2005-2009 Ford Mustang GT and Shelby models 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 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 4.6L 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.
Precision machined steel flanges that provide a tight seal at the head and allows a high flow rate through the primary tubes
