What exactly is happening to make that wonderful sound these cars make at a high RPM gear change. I described it in another post as braaaap pow. Is it all for show or is there more to it? I know the AMG motors do it as well. Probably a newb question but it is a new sound to me.

I think he is referring to the farting sound coming from the exhaust when in Sport or Sport+, and the shifts are aggressive.

turbulence in the exhaust created by cooled air and hot air meeting and cooling off as it travels down the exhaust pipes. when they equalize you get the sound you are referring to. while not a proper analogy it may help to think about thunder which occurs after lightning.

valves close. less turbulence and less air to pass through. they're still there but not as loud.
