No the resonator has nothing to do with emissions.

Correct the resonator tones down the exhaust note before the muffler/ silencer.
Depending on where you live cats are necessary for emissions.

I bought my car from Alabama and had to get it to pass GA emissions.
So I bought a magnaflow hi flow dual pipe cat.
Relocated the glasspack to the tail end and ran piping from the cat back.

If you do it to your car you'll be fine with emissions. My car passed NJ emissions with flying colors.
