I have this same issue. I just installed invidia dp and catback. It sounds like an exhaust leak at low rpm but then starts to whistle and flutter under boost. Almost like a baby EWG lol if that makes sense. All gaskets are new and not leaking. Figured it was from the bigger dp. Idk but it drives me insane.
