After deleting cold start it's gone. Hopefully it's not an MPE issue. If it is, I'm sorry you have to listen to that, because it sounds like absolute garbage.

Oh yeah so there are two distinct drones here (I think he is specifically talking about #2):
1. Cold start drone - solved with cold start delete. Agree with you this is super annoying, borderline embarrassing lol
2. 3k resonance/drone - very noticeable in any sort of straight pipe configuration (valves open). Ever noticeable in 1st and 2nd gear on stock valve control as the valves are open in both those gears. Once it hits third, the valves are closed at that RPM until you really get on it or hit the upper rev range.
He could be hearing it more because MPE has no sound insulation, so it's louder in the valve closed setting and more of that drone is passing through
