I know I picked up around 3 when I got the pipe ran all the way out on my truck. Was getting around 9 with the mufflers dumped under the passenger seat.
Sometimes the best way to learn what works an what doesn't is to do it, I know trucks aren't supposed to be Prius's when it comes to fuel Econ. But why make it worse on yourself? I'm happy with my 15mpg's, considering gas is going back up.
