Secondary Cat Delete NPP Issues

Hello everyone,

I was wondering if the secondary cats function as resonators that dampen vibrations? Bc I was getting this vibration/resonance pitter patter sound towards the trunk after getting my secondary cats deleted, not sure if I need to go to an exhaust shop to get this checked out/or what my solutions are. I still have my secondary cats handy, but I don't wanna get the volume decreased again haha
Let me know if anyone had this issue with their secondary cats.
Attached video of the sound below:
