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

The FLO 601 is a 5" Downpipe Back exhaust for the 2001-2004.5 Duramax Trucks. This will replace the restrictive exhaust system with a 5" high-flow system with a high-flow muffler for street applications. 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 sail through the installation process. This exhaust not only sounds great but will help improve your mileage, torque, and throttle response in your Duramax!
