I just picked up my A6 14' a couple of days ago, and noticed right off the bat that it appears that it has a little more growl to it than my 12' does? is my mind playing games on me, or is it exactly 100% the same exhaust as the previous years? i drove both cars the same day, with all stock exhaust, and both my wife and I agreed that it seemed pretty noticeable the sound difference (for the better) ??? anyone else experienced the same?
