01-07 Chevy/GMC Full Exhaust System

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

The FLO-801NM/Jamo is a 4″ downpipe back race exhaust system for the 2001-2007 Duramax Trucks. This will replace the restrictive OE exhaust system with a 4″ high-flow straight pipe exhaust system. This kit doesn’t include a muffler and is intended for track applications. Just like all of Flo-Pro’s/Jamos 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. It not only sounds great but will also improve mileage, torque, and throttle response.
