The 511004 & 512004 is a 5" turbo-back exhaust system by Mel's Manufacturing 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. The 511004 does not include a muffler and is intended for track driven 6.7's! Just like all of Mel's Manufacturings 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 the torque, mileage, and throttle response on your 6.7L!
