“So if I go out in the garage, crawl under the car with a cut-off wheel and chop out the catalytic converter, and replace it with straight pipe - does the EPA intend to sue GM?”

In certain states where they don;t do emission testing there are plenty of shade tree mechanics who will kindly “fix” a plugged up convertor for free....
They get to keep the “leavings” of course.
