arizona cat laws?
 

are cats required in az? im thinking about a cat delete, if they are required im just going to gut mine. the "filters" or whatever is in them are all broken up and are rattling around in the casing.

I believe it's not a state law, but a Federal law.
So yes, they are required.

If you have an inspection, then it is required.
If you don't have an inspection, it doesn't mean you can remove them.

ehh if i gut them it wouldnt throw a code would it? i always hear about the chevy boys and the vdub idiots gutting them. and i only call them idiots cuz i was googling something yesterday and they sound much stupid then i ever have on here. and i have said stupid things on here,=.
