Description
The FLO-680NM is a 5″ Downpipe Back Exhaust System by FLO-PRO for the 2017-2019 L5P Duramax. It’s the perfect kit if you’re looking to remove your stock components and replace it with high-performance & high-flow 5″ piping from the Downpipe back! 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. You’ll notice fuel mileage improvement, increased torque, and you’ll have a much better sounding 6.6L!
Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
These kits will only fit models equipped with the OEM style 4-bolt flange off the turbo direct pipe!
