FOR 89-96 BMW E30/E36 3-SERIES M42-B18 318 4-1 STAINLESS HEADER MANIFOLD/EXHAUST

Description:

    This exhaust manifold for the 1991-1996 BMW E30 4 Cylinder Engine 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 off-road racing headers are designed to allow the exhaust gasses to flow more freely from each cylinder and combine in a more efficient manner. Tubing has been optimized for the 1.8L and 1.9L 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.
