AND

If gasoline catalytic converters produce CO2 from the CO and hydrocarbons in the exhaust, then isn't it possible that a 60 MPG car modded to run WITHOUT a CAT emits less CO2 than a 30 MPG car with a perfectly-operating CAT?

(Obviously, emitting poisonous gasses such as CO is not a good alternative to emitting CO2, but I am curious what you all think.)
if you have an older car install a newer 3way catalytic converter.

you can get good aftermarket highly rated 3 way converts pretty cheaply (get a California CARB rated 3way converter, don't get a 49state one as those are poorly made)
