Description

Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
Looking to make more power and increase your MPG on your 2011-2015 Duramax? The 864NM 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 Manufacturings 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 doesn't include a muffler and is 'intended' for race applications!
