Diamond Eye K4259A 4" Aluminized DPF-Back Exhaust System 2014+ Dodge Ram 2500 6.7L Cummins

The Diamond Eye K4259A is a 4-inch aluminized steel DPF-back single exhaust system engineered specifically for 2014 and newer Dodge Ram 2500 4-door crew cab short box trucks equipped with the 6.7L Cummins diesel engine. This mandrel-bent exhaust system connects directly to the factory diesel particulate filter (DPF) and provides a complete exhaust solution from the DPF to the rear of the vehicle.

Key Features:

• 4-inch mandrel-bent aluminized steel tubing for maximum exhaust flow and durability
• DPF-back configuration retains all factory emissions equipment for legal compliance
• Single side exit exhaust design optimized for short box applications
• Precision-engineered for exact fit on 2014+ Ram 2500 crew cab short bed models
• CNC mandrel bending ensures consistent pipe diameter throughout bends for unrestricted flow
• Aluminized steel construction provides excellent corrosion resistance at an economical price point
• Includes all necessary mounting hardware and clamps for installation

This exhaust system improves exhaust flow over the factory system while maintaining compatibility with the DPF and all emissions controls. The 4-inch diameter tubing reduces backpressure and helps unlock additional horsepower and torque from your Cummins diesel. Diamond Eye's mandrel-bent construction eliminates the crushing and flow restrictions found in cheaper crush-bent systems, providing smooth internal surfaces for optimal exhaust evacuation and improved engine performance.
