I have one like a whirring rattle, but ironically it happens after 15-20 min of driving and the car needs to be fully warm. Sounds like it's coming through the dash.

I'm afraid the dealer won't address it because I have a Dinan stage III and a free flow Dinan exhaust too so they might blame the slight drone of the exhaust or the upgraded oil cooler intercooler and tune for it, though they are really not supposed to, since it was dealer installed to begin with. I had a video for mine too- ill upload it later for you guys to ponder.
