Have you seen these videos?
MPE with the valves open is a brighter sound, and will have more drone as well, it's a common complaint.
Drone is usually a product of a missing resonator + aftermarket exhaust. I have the stock box with a Fabspeed sport cat and Dinan resonator delete and NO DRONE whatsoever. So drone is basically a function of aftermarket exhausts, for whatever reason, paired with the resonator delete.
