If they do a visual inspection, you're gonna fail even with a cat, since you're not supposed to replace any factory part that has emissions control on it. The front pipe, as you know, is where the secondary cat is.
Most NYS inspection facilities don't do a visual though, and simply rely on the OBD2 to report on the emissions system. Since the O2 sensor is before the secondary cat (in the factory headers), removing the secondary cat downstream from that should not affect the OBD2 reading.
Even if they were to perform a sniffer test, I believe the primary cat would do a sufficient job to pass, but YMMV. I'm not sure if NYS relies on a sniffer anywhere.
