Product: Replacement for GMC Yukon/Sierra High-Performance 2-PC Stainless Steel Exhaust Header Kit
Brand: Auto Dynasty
Color: Polished Chrome
The exhaust manifolds found in the 1999-2005 Chevrolet / GMC Pickups and SUVs 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 4.8L and 5.3L engines. 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.
