I am not 100% sure, but I'm quite certain that adding an aftermarket performance exhaust, (one that is designed to increase horsepower through decreased backpressure) will in fact increase your gas mileage. This is as long as the nice new sound doesnt give you a lead foot. Basically, if you retain the same driving habits, a performance exhaust should improve you gas mileage.
