If you like a loud exhaust this ones for you. My F250 6.2 liter Ford "seems" to run smother and a little more power. No gain in fuel mileage (disappointing). I only had it on for one tank of fuel so my be not sure about a fuel mileage gain yet. Would I put it on again probably not with out an increase in fuel mileage.
