A7 OEM manifold? Yes, but think you need to notch the front engine mount bracket.

No it's not a direct fit. You will need to retrofit a few parts. There is a guide on rosko racing website.

Wait...intake or exhaust manifold.

Hang on... Are you talking exhaust or inlet manifold? I think exhaust, ratty thinks inlet (I think?). we have a 50/50 on being right

Just to confuse things, will a bb1 h22a downpipe fit on an h22a7 manifold?

A friend has got a huge dent in his downpipe & I've got a spare bb1 one.
