Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
The FLO-860 by FLO~PRO 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 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!
