I've seen cases with older trucks where the bed is too beat-up/rusty and a flatbed was built, but I've never seen one on a truck this new. If you really want to go that route, building from scratch is probably the way to go. It seems tacky to me though, sort-of like exhaust stacks on a gas truck or lifting a 2wd truck.
What engine does it have? It seems like most of the Ford guys like to go with a supercharger to make power. I don't think there's much to be had in an exhaust system/fuel system upgrades on an otherwise stock engine. Exhaust systems aren't as restrictive as they were 20 years ago.
