The FLO-1674 by FLO~PRO is a 5" Turbo Back Exhaust System for the 2013-2018 6.7L Cummins. This high-flow 5" kit is built with aluminized or stainless steel tubing and includes a high-flow muffler. 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 cruise through the installation process. Not only does this system sound great, but it will improve torque, throttle response, fuel mileage, and flow while lowering EGT's in your 6.7L.

Ask a Question
  • Will this fit 2017 3500 with air suspension


  • Will you ship to Texas

    We can not ship any exhaust or EGR components to the USA. Sorry!

  • Will this fit a 2016 ram 3500 dual rear wheel crew cab


  • is this from the turbo back ?


  • What type of muffler comes with the 5” stainless exhaust? What difference does it make going from 4” to 5” or why should I opt for 5” over 4” Do I need to install a tip? Also I’m looking for the quietest muffler with almost no power loss. Can in upgrade the muffler in a complete set up if it doesn’t meet my noise threshold.

    Please read our article here 


  • I have a 2019 ram 3500 diesel single rear wheel and I want a complete 304 stainless steel 5 inch exhaust preferably with a black tip because I have the night package on the truck

  • Which muffler does this include

    This will include Flo Pro's flow through design muffler

  • Will this fit my 2017 3500 crew cab with a 6-foot box?

    Absolutely. As long as your 3500 has a Leaf Spring or Coil Spring setup, there won't be any fitment issues.
