6.6L Duramax w/ V-band flange at Downpipe
 
Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
  
The FLO-664NM is a 5" Downpipe-Back Exhaust System by FLO-PRO for the 2011-2015 6.6L 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!

Notes
  • The turbo direct pipe on some of the 2015 models has a 3-bolt flange instead of a V-band clamp. These kits will only fit models equipped with v-band clamp and will NOT work for trucks equipped with the 3-bolt flange off the turbo direct pipe!
