Upgrade your 2013-2018 6.7L Cummins with the AFE Large Bore-HD Series 5" Stainless DPF-Back Exhaust, designed for maximum flow, improved performance, and a deep, aggressive sound. Built from 5-inch mandrel-bent stainless steel tubing, this system reduces turbulence, increases horsepower and torque, and lowers EGTs, giving your truck a noticeable performance boost.

For a perfect OE-style fit, it features bayonet-style hangers that hold up under high heat and vibration, ensuring the exhaust stays securely in place over time. A specially formed end connection allows a seamless attachment directly to the DPF, making installation simple and hassle-free using factory mounting locations. This system is available in three configurations exclusively for 160.5" & 160" wheelbase models: you can order it without an exhaust tip, or upgrade to a massive 6” black powder-coated stainless steel tip or a 6” polished T304 stainless tip for a clean, finished look.

Proudly engineered and manufactured in the USA, the AFE Large Bore-HD Series 5" DPF-Back Exhaust is built for durability, power, and style. Order yours today and let your Cummins breathe.
