DX exhaust manifold vs. Si exhaust manifold

I've just noticed that the 92-95 civic Si manifolds are 4-2-1 unlike the Dx ones which are 4-1. Just wondering if I took an Si exhaust manifold and slapped it on a Dx motor if that would make a difference?

The Si motor is 1.6L while the Dx is 1.5L so I'm guessing the Si manifold would allow more flow but I could be wrong.

Would it be a direct bolt on or would I need to make any mods to it.

If anyone has a stock si exhaust manifold, i wouldn't mind taking that off you? That is, if its fits perfectly.
