Default I've gutted my cat, now getting bad miles

I've planned to get a high flow cat, so I gutted my stock cat and noticed i'm getting bad mpg. It's at 50mpg from full to half full. Anybody done this and get similar results? Just out of curiousity, any reasons as to why it happened this way?

sounds like you damaged your O2 sensor or forgot to hook it back up if you unplugged it.do you have a MIL?
