Ok, had the XLT resonators installed today. Here's the video. I didn't set it up right, LOL, I revved it higher and more times in the "before" half of the video, so it's not apples to apples!
While it may seem meaner without the resonators from outside the car, the drone was getting to me in the cabin. Steve at Solo recommended the automatic XLT resonators, so I gambled. I'm happy! Took the edge off and no more drone, still way better than stock, and no more "fat cans". Check it:
