Shima Performance Exhaust Manifold Headers BMW E46 E39 Z4 2.5L 2.8L 3.0L 01-06
Our long tube off-road header is a Tri-Y design to allow the exhaust gasses to flow more freely from each of the 6 cylinders and combine in a more efficient manner. Tubing has been optimized for the 2.5L, 2.8L and 3.0L 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.
