I don't have the Loudmouth but I have their PowerFlo and can tell you there is not much drone, however PowerFlo is their quietest exhaust and from the video clips the Loudmouth II sounds like it has a lot of "bass" so I would imagine there will be a lot more drone than the PowerFlo. Also since you have an A6 coupe like me that seems like the worst possible combination for inducing drone.
I take it you didn't like the Loudmouth I from their video clip? I know the Loudmouth II is very attractive-sounding because of how smooth it is but I actually liked the aggressive, raspy tones of the Loudmouth I, some people would say it is too much like Corsa though I guess...
