There were several states that received SULEV 328's, but not every 328 in those states is SULEV.
It's possible that the 328i you purchase in other states is SULEV as well. My car is a pre-owned car used as a loaner at a dealership in Maryland. I didn't know it had an N51 for several months.
If in doubt, check the emissions sticker under the hood to see what you have.
