I have had a 2012 Challenger for 3 years and a Pro Charger on it for two years. Last year I had no problem passing my Challenger through smog inspection. Now this year, the DMV is giving me trouble. They are saying the Pro Charger isn't carb legal. I live in Nevada and don't understand what California emissions have to do with Nevada and why all of a sudden I'm having a problem this year? I was wondering if anyone is more familiar with the law and tell if if I'm getting the runaround or not?
