I also drove her M last week. Yes. It's faster now. Its exhaust sound also became more growl and a little louder. Actually M's exhaust sound is louder than my son's G. But M's exhaust sound only becomes loud when really pushing it.
GSF's exhaust sound is even louder. GSF's exhaust sound becomes loud even when just giving a little more throttle and becomes VERY LOUD when really pushing it...
