No, incorrect, wrong, wrong, wrong. As wrong as claiming Annie Lennox wrote a song about walking on propane gas.

nox stands for a single chemical family being tested for: Nitrous OXides.

Petrol-based engine emissions-testing systems aren't even remotely categorized like you listed. The 'bad chemicals' they produce are:

• Nitrous OXides (two Nitrogen atoms and a random number of Oxygen atoms)
• Carbon Monoxide (two Carbon, one Oxygon)
• Unburnt HydroCarbons (one Hydrogen, one Carbon) actually.

These (NOX, CO, HC) are what are tested for in a tailpipe test, also. A three-way cat converts NOX better if you're running a rich mixture, or converts the other two better if you're running a lean mixture. Basic chemistry, replace a cat, adjust the fuel mixture and you can pass an emissions test almost always. California is so hard to pass because of their inspections, which include the most common ways to adjust the fuel-mixture having to be factory-spec.

At least research your claim a little before spouting it off like it's gospel, 'kay?
