The 411021 is a CAT & DPF Delete for the 2007.5-2012 6.7L Cummins Trucks. It replaces your restrictive CAT & DPF system with their high-flow 4" mandrel-bent delete kit. It mounts directly to your OE piping without requiring any modifications and includes a Mel's Manufacturing Downpipe. 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. Since this kit is flanged as factory, it will not match up to an aftermarket exhaust system.
