Enhance the performance, sound, and appearance of your 6.7L Cummins-powered Ram with the aFe Large Bore-HD DPF-Back Exhaust System. Designed for high-output diesel applications, this system features 5-inch mandrel-bent 409 stainless steel tubing to maximize exhaust flow, reduce backpressure, and help lower exhaust gas temperatures (EGTs).
This direct-fit DPF-back exhaust installs using all factory mounting locations, allowing for a straightforward, hassle-free installation with no cutting or modifications required. OE-style flanges, premium band clamps, and bayonet hangers ensure a secure, leak-free seal and maintain precise exhaust alignment under extreme heat and vibration.
Optimized mandrel bends promote smooth exhaust flow with minimal turbulence, supporting improved horsepower and torque while maintaining excellent drivability. Completing the system is a massive 7-inch wrinkle-black powder-coated 304 stainless steel exhaust tip, equipped with a laser-cut stainless steel aFe Power badge and an integrated drain port to resist moisture buildup and corrosion. The aggressive black finish delivers a bold, performance-driven appearance at the rear of the truck.
Engineered and manufactured in Corona, California, the aFe Large Bore-HD exhaust system delivers premium quality, precise fitment, and proven performance trusted by diesel enthusiasts.
