I understand that the Ford Racing header system eliminates the cats, but wouldn't that precipitate a check engine light? If so, is an electronic defeat device available? I had a dickens of a time eliminating the CE light when I removed the cats from my Viper (for racing purposes only I might add).
Aside from that, do the headers really free up that much more power on a stock engine? How about a lightly modified engine?
