If I remove on converter from my car will the car still pass in NY if I have the other 2 still?

No, the downstream oxygen sensor will notice the reduced catalyst efficiency and trigger the check engine light. Also, if New York does a visual inspection, as most other states do, you'll fail for having the converter removed. It's also worth noting tampering with emissions equipment is illegal.
