Also, to add a little more, I just drove to work today with my back seats and all of the trunk crap out of the car since I'm going to the strip tonight.
I sometimes wondered that maybe my car was just doing a good job in muffling the drone, but in all honesty, with all of the stuff out it just sounded better.
I have a smooth sound; no drone.

Unfortuntely when cruising in SD instead of D I see my instant mileage plunge 25% lower from ~32-35mpg normally in D to 24-27mpg and it also makes the throttle a bit too sensitive for rush hour driving along with lots of engine braking.

Hopefully the muffler guy and I can jury rig a solution without resorting to me using SD all the time (which doesn't avoid the problem of when driving from standstill still hearing the bad drone/vibration reving 1500-2000rpm). I'll update later tonight with my findings.
