The only way you can beat the OBD emission test is if your car won’t communicate. If you have a functional CEL thats not on and your vehicle won’t communicate with the test equipment they will generally still give you a sticker. The state has this loophole for newer cars( the new, advanced CAN diagnotics was the problem), they do monitor how many times a shop and individual inspectors sticker problem cars and they know which cars do it. Good luck finding someone to leave the OBD plug out when they run the test(hint hint). I personally wouldn’t and can’t condone any illegal activities but the test can be beat.
