The exhaust manifolds found in the 2000-2006 Jeep Wrangler 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 Shorty Style off-road headers are designed to allow the exhaust gasses to flow more freely from each 3 cylinder bank and combine in a more efficient manner. Tubing has been optimized for the 4.0L 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.
