This exhaust manifold for the 1984-1991 BMW E30 chassis was designed to combine the exhaust gasses from each of the 6 cylinders quickly with a manifold that was cost effective to produce.
The 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.
The Tubing has been optimized for the 2.5L and 2.7L engines.
