RE: headers
yea i think you should get a little bit better gas mileage cuz everything flows more openly. the problem is that you will probably love the sound and will want to floor it more and stuff and there goes your gas mileage

RE: headers
Yea should gain MPG slightly with a full exhaust setup... Unless of course your running a o/r midpipe with no cats... Then, you probably won't gain any... And I haven't noticed my car losing any MPG with the o/r X, but it sure as hell feels like it.
