sorry to elaborate a little as i was face full with lunch and typing short replies!!
if i remember correctly the manifold of a 320 is all 6 together is one unit whereas the 325 is 2 x 3 units. this is the reason why you may need the manifold. so that the bottom of the downpipes meets up with the exhaust pipe coming from the centre box.

i could be wrong thogh
no doubt someone more knowledgable will be on soon.

i use 325 zaust on my 320- nice noticeable flow increase.

325 usually have i piece log manifold.difference is pipe diameter.325 is slightly bigger than 320.

on the 3 320i's i have seen they have one long piece manifold instead.
i forgot the rather obvious diameter difference
sorry bout that

What he said

Some have the 2-peice manifold, and there are 2 sizes of manifold flange on 1-peice manifolds. You'll just need to take a look at the flange on your 320 mani and compare it to the one on the 325.
