does anyone know if 2.0 and 2.5 m52 manifolds the same size as the 2.8?
i ask as i picked up a set off the floor of my scrappy but i have no idea what size engine they came off, it was an e39 though.
exhaust manifold sizes.

I think the M50 is a cast manifold and the M52's are tubular AFAIK
How do you pronounce 'either'? I say 'either', but some say 'either'. Either is correct.

Ferg is correct, the m52 are tubular and these are needed for m50 conversion as they can be cut down to fit around everything.
The cast mani's won't go in and cannot be molested like the tubulars!
I would say that when coupled to a decent exhaust the tubulars would flow much better aswel

A 2 door e30 with 8 cylinders, what could be better

thanks for the replies but thats not what i'm asking chaps.
the tubular manifolds on the m52b20 and m52b25, are they the same physical size as the tubular manifolds on an m52b28?
