The Diamond Eye K4259S is a complete 4-inch DPF-back dual exhaust system engineered specifically for 2014 and newer Dodge Ram 2500 4-door trucks equipped with the 6.7L Cummins diesel engine. This mandrel-bent system is constructed from durable 409 stainless steel, offering excellent corrosion resistance and longevity while maintaining an affordable price point compared to higher-grade stainless options.

Key Features:

• 4-inch mandrel-bent tubing for maximum exhaust flow and reduced backpressure
• DPF-back configuration connects behind the factory diesel particulate filter
• Dual exit design for aggressive appearance and improved exhaust scavenging
• 409 stainless steel construction resists rust and corrosion
• Precision mandrel bends maintain consistent tube diameter throughout
• Direct bolt-on installation with all necessary hardware included
• Engineered to work with factory emissions equipment

Diamond Eye's mandrel bending process ensures smooth, consistent bends without the crimping or flow restrictions found in crush-bent systems. This precision manufacturing translates to measurable gains in horsepower, torque, and fuel economy while reducing exhaust gas temperatures. The 409 stainless steel construction provides a cost-effective balance between the longevity of stainless steel and budget-conscious pricing, making it an ideal choice for daily drivers and work trucks.
