Product Details
This kit from Diamond Eye Performance gives you a 4-inch aluminized DPF-back exhaust system designed specifically for the 2014 Dodge 6.7L Cummins 2500 with a short box, Crew Cab, or Mega Cab. It replaces the factory exhaust from the Diesel Particulate Filter (DPF) back, aiming to improve exhaust flow and potentially alter the exhaust note.
Diamond Eye uses CNC mandrel bending to create smooth bends in the tubing, which helps maintain exhaust gas velocity and reduces backpressure compared to crush bends. The aluminized steel construction offers a good balance of durability and cost-effectiveness for this type of exhaust system. This kit is designed as a direct replacement for the factory exhaust section behind the DPF, making installation more straightforward for those comfortable working on their vehicle's exhaust.
Keep in mind that this system is not CARB approved and cannot be shipped to California. If you're looking to change the sound and flow characteristics of your 2014 6.7L Cummins 2500, this DPF-back kit is a solid option.
