Thanks everyone. I've had the drone with my 2 1/2 inch TTI with H pipe and Dynomax on my 69GTX for years. After reading the posts I ordered a couple Jones 2 1/2 inch, 12" X 4" mufflers, Summit JEX-A4512B, to use as resonators. They're aluminized and a little smaller, just what I wanted. Will report back how they work.

I did exactly as described above and it works great! Drone is gone but still a healthy rumble at idle, much more enjoyable on the highway now. You can put the Jones mufflers in two ways, I put them in the maximum through exhaust mode, still plenty quiet.
