I was about to say that...cats are designed to recduce CO, NOx, and unburnt fuel. Not co2... And yes a good quality performance cat will flow more than your engine, so there really is no gain to be had. I do not believe in the whole global warming(as a way of life, not the theory) but i DO believe in cleaning up the air. If youve ever driven a car without a cat, youll want one back. It stinks and gives you a headache even with the windows up
