I don't know much about how inspections work in Phoenix, but I'd wager nobody even has an exhaust gas analyzer anymore, anyway. Likely their inspections (on pre-1996 cars) are visual only - but don't take my word for it.

Colorado still tests , this thread is not me or my car , but I feel bad for anyone who owns a vintage car in a place that still tests pre OBD2 cars .
Thankfully where I live it's a visual safety inspection only on anything pre OBD2
