This.is your DP catted? I once burned up part of my cat at the track, and pieces of it broke off and ended up inside the muffler, where they'd occasionally rattle.

Turn up radio volumeIf something fell off the catted part of the DP and got into the muffler, what is the remedy?
DP is catted. If something fell off the catted part of the DP and got into the muffler, what is the remedy? New Exhaust or muffler?
Remove the muffler and see if you can shake any pieces out of it. If it is parts of the cat, then you'd probably want to remove the DP and clear out anything else that's left in there. Then you can put it all back, and should be fine.
But maybe get some data logs done to see what kind of AFR's you are seeing in boost. Sounds like you could be running hot (if you find out you are actually burning up the cat).
I once had a couple of cats glow red hot (V8 dual exhaust setup) after a night at the drag strip. On the drive home sounded like I had rocks in my exhaust. Took it to the shop the following Monday and they finished clearing out what remained. Basically ran with gutted cats for a while until I switched to another exhaust setup.DP is catted.

First thing I would check is heat shields around the downpipe. I've heard some aftermarket downpipes can vibrate against a heat shield. If it's not that, take the stock exhaust off and shake it to see if anything falls out or rattles around.
Helps to have a fellow enthusiast designing and making these parts for our cars. He has to deal with them on his personal car so you know they're gonna be a quality fit!Shoot.... Quick flashlight will clear that up...my Baun DP has like 2"+ clearance on every side
