I have a stock exhaust and ASD. The drone was horrible in Sport from ~2300-3000. Put the car in Comfort and it was better.

So is the lack of the resonator the part of the issue or mainly the ASD?

When you say box do you mean something is loose in the muffler?

BTW, I didn't hear a rattle in the video. At what time stamp is the noise?
