just fyi, thats a "328" quad exhaust. it is NOT the same as the 335 quad exhaust. the "drivers side outlet" are definitely not the same for 328 and 335. there are quad setups for the 328, and then there are 335 quad conversion for the 328.
but yes, whether you have a e92 or e90, if you have the mtech bumper, you can change the diffuser piece later. e92 bumpers are the same with each other, and e90 bumpers are the same with each other. just dont try to mix n match e92 and e90.
