This complete exhaust system replaces everything from the diesel particulate filter back, delivering improved exhaust flow and a deeper, more aggressive tone while maintaining emissions compliance.

Key Features:

• 4-inch mandrel-bent aluminized steel tubing for maximum flow and durability
• DPF-back configuration works with factory emissions equipment
• Dual exit exhaust design for enhanced appearance and performance
• Precision-engineered for crew cab short box models only

Diamond Eye Manufacturing utilizes advanced CNC mandrel bending technology to ensure smooth, consistent bends that maximize exhaust velocity and reduce backpressure. This system is designed to deliver noticeable improvements in throttle response, turbo spool-up, and overall engine efficiency while producing a more commanding exhaust note. The aluminized steel construction offers superior longevity compared to standard exhaust materials, making this an excellent value for diesel truck owners seeking performance and reliability.
