DNA Motoring HDS-FM05-46L-SHORTY Stainless Steel Exhaust Header Manifold

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.

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.
