I had the m-tech rear diffuser on my e90 with this muffler installed, so yes it will work. Now, about if it will fit a 328xi, i am 90% sure it will. Toss Remus a PM and ask him. He will inform you. This muffler system is much better sounding then a muffler delete. Plus, you gain power from this remus unit.
