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.

QUESTIONS & ANSWERS

Ask a Question
  • My truck is an extended cab long box 1 ton would this fit

    Yes, designed to fit all wheelbases and cab configurations unless otherwise specified.

  • 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).
