Fits: 2011-2015 GM LML w/ 6.6L Duramax
Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
The FLO-822NM by FLO~PRO is a 4" Turbo-Back Exhaust System for the 6.5L GM Diesel. It allows you to drop your restrictive OE exhaust system and replace it with a high-flow straight pipe exhaust system. 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. It not only sounds great but will lower your EGT's, increase mileage, and increase torque in your 6.6L. This kit does not include a muffler and is intended for race use only!
