My my mode has exhaust on the quietest setting...Coming from a valveless sport exhaust on my old c63 I for one never missed the lack of valves. Once you get used to it, and if it sounds as good as it should, you'll never be using the valved mode anyways. How many times have y'all in here turned down the exhaust note in your my mode?? I'd be willing to bet not many. With the amount of sound deadening the BW cabin has I'm sure it is totally livable inside as well. Keep us posted on how the final versions come along!
