The FLO-640 is a 5" DPF back single exhaust system by FLO-PRO for the 2011-2019 Superduty trucks. This kit allows you to remove the restrictive OE DPF system, which will open up your exhaust system and lower your EGTs. Just like all of Flo-Pro's Exhaust kits, it will come with all the required clamps, pre-weld contour bent hangers, and stronger flanges to help you cruise through the installation process. This kit not only sounds great, but will improve fuel mileage, throttle response, and torque in your 6.7L.
