No drone at all. I only hear pops or crackles on hard accelleration in Sport or Sport+. Normal driving not much changes just a tad louder.
Note that the muffler is different on the 2020+ M550iX. The muffler is louder and apparently has less baffling than the 2018-2019.
I have a remote valve controller too, and tend to run it open occaisionally.
