Have you failed smog and what mods caused you to fail?

[why?]

Especially with these newer cars, you simply aren't going to raise the emissions if you still have the catalytic converters. Even Garms Yaris is absurdly clean compared to any modern car that is larger than a Yaris.

What always makes me laugh is all this smog equipment causes these cars to emit carbon dioxide, which then supposedly is another huge problem(of course it actually is not.)

So tempted to move to a state that does not have any inspections at all. But I know my mechanic really well, and he'll let me get away with anything. Of course in Ma he has to hook the computers up to my car, and do the emissions test, but I am not worried about that.
