When new and in Sport Mode (not N or N Custom), I used to have quite the exhaust crackles off throttle as well as a good occasional single pop/bang when rev'd/shifted enthusiastically at higher RPM. Over the past 1-2k miles or so (now at ~6K), I've noticed that I don't get that anymore. Besides the exhaust bypass flap definitely being open and the sound being louder, it's pretty devoid of any other antics (read quite tame and less... fun sounding). I'd say the Sport Mode crackles are also quite muted if there at all. Put it in N/Custom and it's still all juvenile with the snaps, crackles, and pops. Seems like Sport Mode got less and less "vocal" over time. Anyone having similar experiences?
