Actually, Blind, you only get better gas milage if you replace the y-pipe! 
j/k. Yeah, it helps gas milage. Headers provide better exhaust scavaging so it requires less throttle to get the same power. As far as proof, I will have to see if I can dig up my old UTI books and scan em for ya. Give me a day or 2.
