Exhaust upgrade

I have a 99 f 350 crew cab duallie that i want to upgrade my exhaust. Mileage is my main priority, power and a more agressive sound would be cool.Any suggestions or recommendations on size and manufacturer would be appreciated thanks Scott.

any 4" pipe should be fine. Removing the cat is cool too for milage concerns. But if your gonna have alot of performace stuff on it in the future I would look into a 5". Not to mention if you take out the muffler it will sound really good to

Look into a 4", the 5" is for sound, it has nothing to do with performance down the road. Everyone thinks that 5" is better for high HP. I make a fair bit of power and I use a 3.5" down pipe to a 4" exhuast.
