If the post-cat O2 DTC is turned off, that might be picked up from the OBDII port like Chuck said.

In your case it is possible that the intakes fail visual or the HFC's don't pass smog. Best bet is to simply have the ECU put back to stock temporarily or at least make sure all your DTC codes are ready (i.e., not turned off in the uprev menu).
