Does your county/state do a "sniff" test where they sample the exhaust coming out of the back, or do they do an OBDII readiness check? If they do an OBDII readiness check, you should be fine, since it is the first set of cats that are monitored. If they do a "sniff" test - I would say, how many miles does the car have? If the O2 sensors and the OBDII internal sensors do not show a Check Engine Light, you might be OK, but I don't have any experience, maybe someone on here has front cats only in a state that does a sniff test.
