no, if anything it would increase your milage.. altgough once you install one of those things you tend to want to hear it more and you tend to be heavier on the gas.. so you use more fuel that way.

I put headers and dual exhaust on a Chhevy pickup I have. That helped the gas mileage. It also made it a little faster and it sounds real good.

Exactly Thomas, just like Louis stated the dual exh. can only help w/ the gas mileage. But, you do get into the wantin to hear the exh. tone more and therefore get into the usage of more gas that way.

Good luck!!!
