The exhaust manifolds found in the 1997-2005 the Pontiac Grand Prix, Buick Regal, Chevy Impala and Chevy Monte Carlo 3.8l Supercharged V6 models were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 3-1 Long Tube off-road headers are designed to allow the exhaust gasses to flow more freely from each cylinder bank and combine in a more efficient manner. Tubing has been optimized for the 3.8L 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.
