Hello,
My name is Jim I have a 1982 320 E21 and I'm in the slow process of putting a M2025 engine into. I would like to fit a tubular exhaust manifold with single exit. My question is will this type fiscally fit onto and into My car?

Hi Jim, I'd say "no" because that is from an E30 and not an E21, but apparently someone has got one to fit. I'm at work, so can't really do a search, but see what you find.

Manifolds for the M20B23/20 from the E21 will fit, the ports are ever so slightly the wrong size, but it cures a fair old headache so I wasn't all that fussed.

Then it's custom exhaust from the manifold backwards.

I have that setup on my M20B25 swap and it seems fine to me.
