I hope that is what I'm hearing! Can definitely live with it if that's what's going on. I guess I mainly noticed it at lower speeds, when I would have to be in the lower rev range. Soot is the "air under paper" sound, correct". Almost a hybrid rattle/flutter sound?

Freaked me out, though . I have a GTO rt now, which makes a few noises, but not like that.
