Hey all, I've got a 2013 3.8 rspec m/t with about 900 miles on it. For the past 200-300 miles, the car has been making a pretty audible whistling noise under heavy acceleration from lower rpms (less than 3k, above which the noise ceases). It sounds like there may be a leak somewhere? I can make a quick video if need be, I just figured I'd post here first to see if anyone's had a similar problem. Any feedback is appreciated.

Probably the intake sound that's piped into the cabin. I hear it too, sometimes it's almost similar to a supercharger whine.
