Mel's Manufacturing Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
The 431108 & 432119 by Mel's Manufacturing is a 4" Cat-Back exhaust system for the 2001-2005 GM trucks with the 6.6L Duramax. This system replaces your restrictive OE exhaust with a 4" high-flow system with an in-line muffler from the catalytic converter back. 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 sail through the installation process. It not only sounds better but it will also improve your torque, throttle response, and mileage!
