Info

Flowmaster's Force II DPF-Back exhaust system for the 2011-2015 GM 2500HD and 3500HD trucks is perfect for the person looking for mild to moderate sound levels with all of the performance benefits that you would expect from Flowmaster. This bolt-on emissions-legal system for the 6.6L Duramax diesel engine features DOS (Dual Out Side) mandrel bent 4.00 in. stainless steel tailpipes with 5.00 in. ventilated 304S stainless steel tips. It is designed to fit all wheelbases. The system connects behind the factory DPF unit and utilizes a single inlet, dual outlet "Power Chamber". Due to space limitations and tubing size, this system requires removal of spare tire which is not uncommon for these applications. The exhaust system is manufactured in the USA and is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all of the necessary parts and hardware for installation.

  • Stainless Steel Construction
  • Dyno Tuned For Maximum Performance
