The actual sound is difficult to capture in video, and I am sure that the Dinan exhaust sounds better than what is coming through the video. I also have an M3 (F80) and installed the Dinan intake, x-pipe, and exhaust - it is noticeably different than stock. I have been extremely happy with it, put it on about 6 months after the original car purpose.

Haven't fully made up my mind with exhaust options for my M2C - AA, Akra, and Remus have all been options. And while I haven't completely ruled out Dinan, they are taking entirely too long to get this to market. Much smaller and less known companies are beating them to market. And while their addressable market-share for the M2C is going to be much less than other models, I think they are missing a large opportunity caused by the delays... (same with MPE)
