[3002 tii]

I’ve passed catless in NY, NJ and CT. All have similar checks, they’re supposed to do visual but most rely just on whatever the OBD says. All allow 1 N/A or failure. I’ve passed using both tunes and o2 sims. NY is annoying because of safety and u have these local idiot gas station shops trying to sell you on bs work. NJ DMV is nice because it’s emissions only (and free) but they do have cameras on the ground you drive over. But those operators rarely pay attention to the tv’s and go straight to OBD readings. You can always go to a private shop and pay few bucks more...
