Default Stock Cats - any rattles ?

I have what sounds like an exhaust rattle when the car is cold.

It only happens at a certain rpm, and only for a brief moment while accelerating.

After everything warms up the rattle goes away.

With the car up in the air on a lift, I have shook, banged, and inspected every suspension component, exhaust component, and inspected everything I can think of or identify.

Has anyone experienced this?

Yeah I have it with kinetix cats, only when the car is cold

Did you change out stock cats and then re-install them?

Anything is possible. Stuff inside the catalytic converter can rattle.
