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.
