Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.
The FLO-801NM 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 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.

Will this work with my stock down pipe and do I need a tune to run it ??? I have an 07 LBZ no def on it
This is a down pipe back exhaust so it will work with the stock downpipe but you'll need a tune to account for the removal of the DPF (unless the DEF system has been tuned out).
