This is actually amazing, California SMOG laws were written by a complete idiot. Theyâ(TM)re so strict that they literally prevent you from modifying your car in a way that produces less pollution. I had a project a while back to increase the gas mileage of my car and reduce the emissions but had to shelve it ironically because CARB doesnâ(TM)t care how much emissions your car actually produces, only that it is âoestock,â or you pay them a lot of money (tens of thousands of dollars). Itâ(TM)s actually corrupt as hell, but thatâ(TM)s California for ya...
