in addition add a pair of glasspack type muffs alongside the leaf springs to act as resonators

this is probably your best bet, as the drone RPM/speed has to do with the resonant frequency of the pipe, which is dependent on it's length (think of a church organ) another option might be to try the dynomax VT series mufflers...

It came with DynoMax Turbo mufflers. They are oval, and the body of them is 20 inches long
That's strange to me as my 66 Coronet convertible w/440 RB; Dougs 2" headers and 2.5" exhaust has no drone whatsoever. I wonder if the 3" pipes is a factor? Or maybe how their hung under the car?
I've been recommending these mufflers since I put them on the car thinking they were the best, but maybe not...
These are they -

Ive been wondering if some of the drone we all are fighting is the actual muffler is acting like a drum. Maybe by wrapping some fireproof blanket of whatever and then putting some band clamp that you can tighten TIGHT around the muffler to take the high (low?) frequency vibration out. I havent found a big enough fiberglass blanket yet to try it myself.

Thanks for all of the replies so far, as I will be trying some of these suggestions to get my exhaust OUT OF THE DRONE ZONE!!!!!
I wish I had seen this post before I bought my TTI system. I have a 70 Charger R/T. I just put on the same system you have and it's exactly the same, terrible drone at about 40 MPH. I called TTI and they said they had never heard of a issue with drone with this system. Apparently I'm not the only one.
Have you tried anything yet? I replaced the Dynomax Super Turbos with Thrush Turbos. Same size but different internals. It helped a little but not enough.

I've noticed the last few times I've driven my Challenger that used to drone, that it has stopped. Nothing has changed in the TTi 2.5 x pipe exhaust system. I'm glad the drone was annoying.
