M2 6mt exhaust flaps?

Hello everyone.

Very happy to say that I finally received my M2, after 6 months from ordering and paying a 10% deposit (yes I know but there's only one dealer in Kuwait and this is how it works). Anyway, I'm loving the car, it is by far my favorite car I have owned in my 17 years of driving.

No complains just the usual comments which I don't mind. However, I noticed that there's not much difference between comfort, sport and sport plus when it comes to the exhaust sound. It sounds sweet but really couldn't tell the difference. Perhaps something wrong with the flaps/cutouts? Today I tried the "hidden exhaust" mode by driving in comfort with MTM and it works. Actually, that was the only time I felt a difference. Will have it checked when I take it in for the first service but I was wondering if the flaps are viewable from the back? Is there any way I can physically confirm whether or not they are opening/closing?

Congrats! I have not noticed any difference between modes. The "hidden" mode is the loudest for sure.

Does anyone even preview their post anymore before posting? Neck hurts looking at that pic LOL kidding congrats on the new whip!

For the modes, can't really tell the difference in sound. Maybe when cruising on the highway in comfort will be the quietest. For the exhaust flap being open, you won't notice this until you give it full throttle. Basically the way you can tell if the flap did open is you'll notice residue on both sets of exhaust tips. Flap not open, you will only see the right set of exhaust tips have residue stuff

Lol, sorry about the photo guys had it posted from my mobile. Here's a video of the sound, 1st 3 revs in comfort, following 3 revs in sports plus, final 3 revs in comfort with MTM (DCT short press).

100% agree with you. I dont notice any major differences in exhaust sounds either in low to mid range revs. However, the exhaust burbling is most noticable in the "secret" comfort MDM mode, followed by Sports +, Sport, and then "normal" Comfort mode. So the exhaust burbling I find are different between the normal modes.

But this is great for daily commuting in Comfort mode but get the nice crackle and pops while putting around town.

However, I imagine the exhaust revs would be much more noticable with MPE or other aftermarket systems. Either way, stock sounds plenty good enough for me. Much louder and way better tone than my previous car (435) with MPE.

Congrats on your car =)

A couple of follow up questions.

1. I know the car doesn't have a boost gauge but them why is there a selection for pressure unit (psi/bar/kph) under language and units.
2. The car has comfort access and under the options I have driver door, all doors and comfort entry. What is comfort entry? Without selecting it I do get keyless unlock/lock of the car.

Congrats on the car, I spend 90% of the time in the secret comfort mode as well. Haven't really listened out for the other modes. I know Sport and Sport + does sound louder in the car via the speakers.
1) I believe the pressure units are for tyre pressure read out.
2) Comfort Entry, When you unlock the car by pressing the button on the remote control twice, the windows will be lowered when you open the door. This helps you get in the car in tight spaces.

Hope this helps.
