Please note that on 6.2L Platinum and Harley Davidson edition F-150s, modification to the factory exhaust flange will be required. The Roush Performance Cat Back Exhaust is the perfect upgrade for your F-150. Featuring an open-chambered designed muffler, this Roush Exhaust features an aggressive sound that is unique to Roush without the boom/drone found on many other aftermarket exhaust systems at cruising speeds. Roush Exhausts are made from stainless steel and are finished with a chrome flashing process. The exhaust tips are embossed with the Roush logo. Roush Exhausts are completely bolt on and can be installed with minimal effort. All necessary hardware and instructions are included. The part number for this item is Roush 421711 and it fits 2011-2014 Ford F-150 (3.5 5.0 and 6.2 Raptor Models).
