Equal length sports manifold for BMW E60, E63 with an engine of the N52, N53 series (2004 - 2012 year of production). It’s made of high-quality 304AISI stainless steel. This model is also compatible with BMW Z4 E85/ E86, Z4 E89, F10, F18, F01 with an engine of the N52N, N53 series (2008 - 2012 years of production) but you will need a minor adjustment of the silencer’s inlet pipes. The design with continuously curved pipes of a particular length, which equal the distance from the exhaust valves to the point of the peak resonance (a place where the manifold is installed), creates the most comfortable gas emission and additional discharging in the exhaust system. This allows improving the blowdown of the combustion chamber of each cylinder at medium and higher engine speeds. Such V8 manifold increases the capacity of the engine with limited indicators by 20 - 27 hp. and improves the quality of the torque curve. This manifold gives the exhaust system a more intensive and aggressive sound. Besides, it’s used as a credible alternative to catalysts’ removal.
