It may very well be, and the engine sound could reach the exhaust. No codes thrown though, and the car runs fine. Not sure what it is, really. It does sound a lot like a horrible exhaust drone but it's not quite drone. Especially given the fact that it only appeared after installing Cobb (Stage 2+ Aggressive)...
