Fits: 2011-2015 GM LML w/ 6.6L Duramax & V-band flange at Downpipe
Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
The FLO-664 by FLO-PRO is a 5" Downpipe Back Exhaust for the 2011-2015 LML. This kit allows you to drop out your restrictive OE exhaust system and replace it with a high-flow system that includes 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. This exhaust system not only looks and sounds great, but will improve your mileage, throttle response, and torque in your LML.
