It is a stock N55 M2 (minus a few cosmetic touches). I brought it in to the dealer, but they won't look at it for a week and I'm left wondering when I will get my car back/how serious this is. |
Since the sound is only coming from the left exhaust pipe, I would say there is something loose in the actuator valve.
