2015.5-2016 Duramax 4" Downpipe Back Exhaust w / Muffler (431018 / 432018)

The 431018/432018 by Mel's Manufacturing is a 4" Downpipe Back Exhaust System for the 2015.6-2016 LML. This kit allows you to drop out your full OE exhaust system and replace it with a high-flow street kit. 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 includes Mel's Manufacturings High Flow Muffler which is a perfect setup for street driven trucks. This exhaust system not only looks and sounds great, but will improve your mileage, throttle response, torque, and flow while lowering EGT's in your LML.
