N20 428i Exhaust Help

Looking to make my 428i sound better, what should i do? Muffler Delete, Resonator Delete, or both?
I went to an exhaust shop and the told me that swapping out the stock muffler for a smaller muffler will make a noticeable difference, and that is what i am planning on doing. I'm getting lowkey burbles in Sport and Sport+ modes already but was also wondering if there was a way to make them louder and more aggressive.
Any recommendations?

Get a catless downpipe and an MPE exhaust.

Downpipe and bm3. If you want more, get a cutout, so you don't have to be obnoxious all the time.
