Turbo cars are more picky about having back pressure than NA cars. Loss of torque from doing a muffler delete on a 328 shouldn't be all that noticable.
BTW, your AA exhaust is basically a muffler delete. A very expensive muffler delete.

Definitely not substantial, I wouldn't think I would be able to tell before/after anyway lol. You will also shed lbs which will help with acceleration.
The AA exhaust comes with a resonator, or you can call it a "small" muffler. Not exactly a muffler delete and it is a lot tamer. Muffler delete is LOUD... inside and outside. Not sure if its appropriate for a 328i hahah.
