Looking to make more power and increase your MPG on your 2011-2015 Duramax? The FLO-864 by Flo~Pro is your answer. It allows you to remove the restrictive OEM exhaust system and replace it with a free-flowing 4" exhaust system from the downpipe back! Just like all of Flo-Pro's 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. On top of increasing power and MPG, you will also increase flow which will help in reducing your EGT's!
