Mel's Manufacturing Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.

The 431013 & 432013 by Mel's Manufacturing is a 4" Cat-Back Exhaust System for the 2011-2015 LML. It allows you to drop your restrictive OE exhaust system and replace it with a high-flow exhaust system that utilizes a performance muffler. 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. It not only sounds great but will lower your EGT's, increase mileage, and increase torque in your 6.6L!
