Ok guys, I guess this may have been answered before, couldn't find any definite answers though.. so..
Basically I have a 320i cabrio (from 88 - pre face lift), currently with a standard 3 piece system, but both my back box and centre box need replacing. Needs a new system - mainfold back basically.
Am i right in thinking that both a 325 or a 320 exhaust (2 piece system or 3 piece system), regardless if its from a cabrio/2 door/touring etc will all fit? I have the twin pipes btw..
Thanks for any answers clearing this up, would really like to buy a new 'zorst but wanna make sure its gonna fit!
Exhaust help..

As long as the manifold stud spacing is the same then they should all fit.
The 325i had 2 size manifolds - one has the same stud spacing as the 320i manifold and one doesnt.

Complete ststem should fit ,if the manifold fits, but I ran into problems once trying to fit an apparently identical 320 rear box to a 325.
The 320 pipes were less than 1mm smaller and wouldn't go together where the rear section joins the front.
