The exhaust manifolds found in the 1998-2002 Chevrolet Camaro and Pontiac Firebird/Trans Am were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our long tube 4-1 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 LS1 5.7L(357ci) 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.
