At the moment it's got a stainless steel exhaust, but want to get either a genuine me one, or a btb/racing dynamics one but finding it very difficult to find one. Can anyone advise or help me source one.
I've seen some on race car.com, the rear box says that tailpipes are 76mm with double pipes, is this the correct size? But can't find a twin pipe middle center section, did they come with a double?
I've currently got a btb manifold so wanted to get the full system, or shall I just get a genuine bmw one? Who is the genuine manufacturer?
Any advise or recommendations?
Thanks
