Can it be the cold weather that causes the car to make exhaust sound?
It has more popping and crackle sounds than before.
With all the windows up on sport plus mode, it used to sound like quiet bubbles but now I can clearly hear the crackles and when windows are down, it sounds like there's gunshots going on outside!

Noticed the same with mine. Had it in for a recall and thought there was definitely a difference to the exhaust. I thought my mind was playing tricks on me - but perhaps not. I am loving it though!
