I smell exhaust, but there is no exhaust leak, and the smell is when the car is running, and for a little while when the car is off?
Do some aftermarket mufflers do this?

Other ways, hopefully like hitting it with a broomstick, and seeing if it's hollow is kind of what I'm aiming at.

I understand this isn't really going to help you, but I can easily tell if a street car has a cat or not. It just gives off a certain smell when there is no cat on the exhaust.

take a wrench. hit the cat, not your pet cat.... and you'll know if its plugged or hollow.. Thunk noise is plugged (Not gutted) and its just totally obvious...

I was just going to mention what IROC5.7 said. My way to describe it, is like a boat. Those don't have cats or mufflers or anything. Pure, raw, mostly burned hydrocarbons.
