The exhaust manifold found in the 1992-1999 BMW E36 chassis was designed to combine the exhaust gasses from each of the 6 cylinders quickly with a manifold that was cost effective to produce. 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, 3.0L and 3.2L 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.<br><br><b>Package Included:</b><li>1 x Set of Header Exhaust System, Gasket(s) and Bolt(s)
