Rattle noise on throttle lift

[Bman5150]

I've got a 2023 GT automatic with the active exhaust. I noticed the other day that when I lift the throttle either when i'm driving or just blipping the throttle, I get this ticking/rattle noise as the RPMs come back down. Could it be the active exhaust flap(s)? Seems like it is coming from the passenger side rear area, which is one reason I thought it may be the active exhaust. I do not have any sort of check engine or MIL on and the car drives great. Just an odd sound.

just a thought get someone to sit in car and rev it same as when noise is there get under car and check if its coming from a loose baffle in each muffler
also the resonator do same
you could also {when motor/exhaust is cold} hit each of them with the palm of your hand or rubber mallet
i have had this happen on new smitthys mufflers once worth a try
good luck
