The Ford/Shelby relationship lives on, and has evolved from Mustang mods to truck mods. This mash-up starts off with an already capable Ford Raptor and adds a Shelby Borla exhaust, Shelby leather interior, custom wheels with 35-inch Goodrich All-Terrain tires, three graphic kit options, and a 2.9L supercharger. The 2013 Shelby Raptor ($18,000+) horsepower is boosted from 411hp all the way to 575hp.
