Yep. If you really car for the environment you would be driving a Prius. I too feel that today's cat technology has caught up to the performance levels of today but most high flow cats still throw codes and most feel what's the point. I also feel that today's v8s make less hydrocarbons uncatted vs catted v8s of 20 years ago. Now, if you go with a can with any amount of lope you pollute even more. This website is full of members that don't give a rats a$$ when it comes to cats or no cats. I feel that if you don't care then at least get a proper tune and keep the vehicle well maintained.
Back on subject of the op now.
