IM a obd2 and safty inspecter in NC and in your case its a 93 wich means you are safty inspection only not obd2 you dont get pluged up to a computer and sent to the state gov.
I dont know about your state.
IN NC I would only go under your truck and "look" and if i felt like a dick and did not get any the night beffor than i would fail you for not having it.
but 99% of the time i would not give a **** and pass you with out looking at any thing. BUT if its relly loud
(after removing cats) the inspecter will know right away and look...I had a super charged big block cobra come in and it was relly loud my boss told me to fail it I DID not want to but...)all he had was borlas and turn downs
