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. This exhaust system not only looks and sounds great, but will improve your mileage, throttle response, and torque in your LML.
Note: This kit will only fit an LML with the V-Band flange of the downpipe. If your LML has the 3-bolt connection at the downpipe you want to use the 2015.5-2016 Duramax Kits!
