aFe Large Bore-HD 5" 409 Stainless Steel DPF-Back Exhaust System
For 6.7L Cummins Ram 2500 & 3500 (2013–2018)
Enhance your 6.7L Cummins-powered Ram 2500 or 3500 with the aFe Large Bore-HD 5" DPF-Back Exhaust System, designed for maximum performance, durability, and precise OE fitment. Constructed from 100% MIG-welded 5" mandrel-bent 409 stainless steel tubing, this exhaust system improves exhaust flow, reduces backpressure, and lowers exhaust gas temperatures (EGTs) for enhanced engine efficiency and performance.
The system features a specially formed end connection that attaches directly to the DPF, ensuring a precise and leak-free installation. OE-style bayonet hangers maintain stable pipe alignment during high heat and vibration, delivering a long-lasting, OE-quality fit that will not change over time.
Smooth mandrel bends reduce turbulence to optimize horsepower and torque. Designed for direct-fit installation, the Large Bore-HD exhaust uses all factory mounting locations, providing a quick, hassle-free upgrade for 160" and 160.5" wheelbase trucks.
Manufactured and engineered in Corona, California, the aFe Large Bore-HD exhaust system combines premium construction, OE fitment, and reliable performance for your Cummins truck.
