The FLO 1648 is a 5" turbo-back exhaust system by FLO-PRO for the 2010-2012 Ram 6.7L. It replaces your restrictive OE exhaust system from the turbo back with a 5" mandrel-bent exhaust system. 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. The FLO-1648 includes a high-flow muffler and is the perfect setup for the street-driven 6.7's! This kit not only sounds great but will improve the torque, mileage, and throttle response on your 6.7L!
