So long as you run both of the O^2 sensors - one upstream and one downstream of the high-flow cat- and aren't running a slobbery rich A/F ratio, OBD II and the sniffer should be perfectly happy.

Although my DC4 is still stock insofar as drivetrain is concerned, I have found that with my previous cars, giving the catalytic converter enough "drive time" to build up heat prior to testing helps NoX and CO^2 emissions at idle.

Every little bit helps.
