Diamond Eye K3320S 3" Stainless Steel Cat-Back Single Exhaust System

The Diamond Eye K3320S is a high-performance 3-inch stainless steel cat-back exhaust system engineered specifically for 2004-2008 Ford F-150 trucks equipped with the 5.4L engine. This single-exit system delivers improved exhaust flow, enhanced throttle response, and a deep, aggressive exhaust tone while maintaining excellent durability.

Key Features:

• 3-inch mandrel-bent stainless steel tubing for maximum exhaust flow and corrosion resistance
• Single rear exit configuration for a clean, streamlined appearance
• Precision-engineered for 2004-2008 Ford F-150 5.4L V8 engines
• Mandrel-bent construction maintains consistent pipe diameter for optimal performance
• Stainless steel construction resists rust and corrosion for long-lasting performance
• Bolts directly to factory catalytic converter location for straightforward installation
• Includes all necessary hardware and clamps for complete installation

This cat-back system is manufactured using CNC mandrel bending technology to ensure consistent quality and precise fitment. The stainless steel construction provides superior longevity compared to aluminized steel systems, making it an excellent choice for trucks in harsh climates or demanding applications. The 3-inch diameter tubing reduces exhaust backpressure, allowing your 5.4L engine to breathe more freely and potentially improving both horsepower and fuel economy.
