Haha, yes, I came to the same conclusion yesterday. It is particularly noticeable when in Sport Plus and accelerating hard, probably because they are piping into the cabin a noise which is pretty heavy on bass. Nice job BMW...if you really feel the need to artificially feed exhaust noise into the cabin, at least take the time to make sure the speakers can handle it!
