"Since the donor was a non-M, I would wager there was never a mount added for the rear of the "M3" muffler.
Thusly, you'd need to find a way to mount an M3 muffler to a 325i hanger setup, and the 325i clamps wont fit around an M3 muffler.

Yep, just dealt with this on my MTech. Another issue I had to deal with was making it all fit while utilizing the stock MTech exhaust opening in the rear valence. I also ended up having to "modify" an e36 clamp to make sure it didn't rub on the spare tire well yet fit a twin tip exhaust in the small MTech opening. Ugh!, tight clearances. One small thing after another.
