I got an Evolution DP from HP Autosport w/200 cell cat.

Then I bypassed the fake engine noise and the car was too quiet and non inspiring so I ordered the M sport muffler.

I then added the CF tips for a beautiful looking system and the sounds are amazing. Fairly loud and deep sounding at startup.

Low RPM's in town or freeway are deep and exotic sounding. BMW must have spent so much time perfecting the sound. It sounds amazing when you are outside the car or have the window down. Inside the car its very reasonable with NO drone on FWY.

I have the stock mid-pipe with 2 resonators.

Deep low rpm, nice smooth sounding mid-ranger with great WOT sounds
