Choose your diameter. Free the flow. Let your 6.7L Cummins breathe. This Stainless Downpipe-Back / Turbo-Back Race Exhaust System is engineered for 2013β2018 Ram 2500 and 3500 pickup trucks equipped with the 6.7L Cummins. Designed for off-road and competition use, this system removes restrictive factory emissions components to support improved exhaust flow and performance potential.
For off-road/competition use only. Race tuning is required.
Factory exhaust systems can restrict flow due to emissions components and smaller-diameter tubing. This upgrade replaces those components with large-diameter 4β or 5β mandrel-bent stainless tubing, reducing backpressure and supporting cooler operating temperatures in tuned or competition applications. Available in multiple configurations, including full turbo-back setups, this system is built for serious performance builds.
