...trying to justify

I actually drive a lot, so if I get 1mpg better I'll save over 300 dollars per year.

I havent noticed much MPG change because my foot is always in it these days it seems.... I think it does do a little better then stock on the hwy though. your tune will have more affect on mpg than just headers.

headers are more of a hp mod vice mpg improver... I think at best you may gain a full mpg.
