Retains factory front muffler (resonator). From the 35" BF Goodrich tires to the cast aluminum SVT control arms, the Ford Raptor has re-defined off road trucks. All that's missing to complete this street-legal Baja prerunner is a high-flow performance exhaust to unleash the engine's full potential, and who better to supply it than Borla the world's most winning exhaust. Borla's Cat-Back exhaust (PN 140383) for the F150 Raptor '10-'14 draws from decades of winning racing experience from the Baja 1000, Best In The Desert, CORR and other top venues, resulting in a world-class off road system. Utilizing Borla's patented, straight-through Multicore technology, Borla engineers were able to achieve a 13% increase in flow while reducing the overall system weight 18%! And they made it look better too. Gone are the boring factory single wall, unpolished tips. In their place are dual 4" polished T-304 stainless steel tips with handsome rolled edges that enhance the Raptors brutish good looks. High-quality T-304 austenitic stainless steel tubing is mandrel bent by computer-controlled CNC machinery to ensure maximum flow and a perfect fit. And while fit finish are great, it's the trademark Borla sound of power that really captures the essence of this premium exhaust. A hearty rumble rings through every time you get on the throttle, slightly louder than stock with no cabin resonance. Like all Borla street systems, this exhaust is backed by Borla's famed Million-Mile Warranty. That's 50 years of off-roading 20,000 miles a year! Engineering innovation, high-quality materials and state-of-the-art manufacturing make it easy to see why Borla is THE choice of performance enthusiasts worldwide.
