17-19 Chevy/GMC Full Exhaust

Flo-Pro/Jamo Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.

The FLO-680NM By FLO-PRO/Jamo is a Downpipe-back exhaust system for the 2017-2019 L5P w/ 6.6L Duramax. It’s the perfect kit if you’re looking to remove all your stock components and replace it with high-performance & high-flow 5″ piping. Just like all of Flo-Pro’s/Jamo 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, improved flow, lower EGT’s, and you’ll have a much better sounding 6.6L!
