How to tell if DB killer/cat is in this exhaust?

Looking at a used 2022 G310r with a MIVV exhaust - no mesh screen on it, any way to tell online/in-person if the DB killer/cat is in it? I guess if its super loud that means its not, but anyone have any guidance?

I would like the DB killer/cat to be in it
