'03 Tahoe Catalytic Converter

I was looking at a 2003 4X4 Tahoe, ex cop car today. It came from out-of-state, [NM], where Cats are not required, I'm told. I hear they are required in AZ, where it would have to be registered.
When I looked underneath, I saw one big muffler, both exhaust pipes fed into, and a single 4'' exhaust pipe out the rear that looked factory.
Motor is a Vortec 5.3. Could there be a catalytic converter inside, or would it need to be installed for AZ ADOT/MVD regulations?
