e90 petrol engine exhaust back boxes

evening all.

im still on a quest for a twin tail pipe exhaust.

so... do all petrol engines have the same exhaust bore? would a 325i back box fit on a 318i?

Well the BMW performance exhausts have different ones between 325i and 318i so I would say all are not the same.

You could either:

Get a 325/330i one and get it cut and welded on
Or
Get a double exhaust tip and cut the old one off + Get the new one welded on.
