This high performance exhaust manifold for the BMW E9 CSL with the M49 engine has True Equal Length primaries. All primaries have a length of 600mm exactly. The wall thickness is 1.2mm as standard (possible up to 0.7mm for the inconel version). The diameter of the primaries is 50.8mm. The 6 in 1 merge collector is made at an angle of 12 degrees to guarantee optimal flow. In all our merge collectors you will find a nicely finished cone, to improve scavenging and therefore a better functioning of the engine. With this system you bring your BMW E9 in top condition. Give your E9 its full potential!

This exhaust manifold is available in stainless 304 (Celeritech's choice), Mild Steel for the historic look or Inconel in 0.7mm wall thickness for ultra light weight.

Are you looking for those top-quality headers, but do you want something unique? There is always the option of a digital 3D-scan of your own car to develop you your own one-of-a-kind custom designed exhaust manifold. Check out our custom service page to see what we can do for you.
