Catalytic converter racket or collusion ?

What is your question?

Why can't someone who lives IN California get a catalytic converter that doesn't cost almost as much as the car its on ? One can get an aftermarket converter in 49 states for as low as $ 68 but if you have your car registered in California, you're forced to go to the dealer ? Why doesn't anyone else sell this part cheaper ? If we didn't owe money on this car ( 5 payments ) we could register it in Nevada, get the part cheap and drive it all we want. I don't get it. Did someone get paid off to have this law passed so that car owners get screwed only in this state ?
