I've deduced that the drone is primarily in Comfort Mode from 1500-2200RPM in just about every gear. It's pretty much cut in half when I'm in Sport Mode. While driving in Sport Mode all the time may seem like fun, my gas mileage will be murdered even more so than it already has been with my now city based commute. I've decided to head back to the exhaust shop tomorrow morning and have them weld in a couple J-pipes to absorb the resonance and kill some of this drone. I've had this work done before and works extremely well. Will upload another video on Monday when I get a chance to.
