Diamond Eye K3322A 3" Aluminized Dual Cat-Back Exhaust System

The Diamond Eye K3322A is a complete 3-inch aluminized steel dual cat-back exhaust system engineered specifically for 2004-2008 Ford F-150 trucks equipped with the 5.4L engine. This mandrel-bent exhaust system is designed to increase exhaust flow, reduce backpressure, and deliver improved horsepower and torque over the restrictive factory exhaust.

Key Features:

• Precision mandrel-bent 3-inch aluminized steel tubing maintains consistent pipe diameter through bends for maximum flow
• Dual outlet configuration provides aggressive appearance and enhanced exhaust scavenging
• Aluminized steel construction offers excellent corrosion resistance and durability at an economical price point
• Direct bolt-on installation with all necessary hardware and clamps included
• Engineered to work with factory catalytic converters for emissions compliance
• CNC-manufactured components ensure precise fitment and quality consistency

Diamond Eye's mandrel bending process prevents the crimping and flow restriction common with crush-bent exhaust systems, allowing exhaust gases to exit more efficiently. This cat-back system replaces everything from behind the catalytic converters to the rear of the vehicle, transforming both the sound and performance characteristics of your F-150. The aluminized steel construction provides long-lasting protection against rust and corrosion while keeping costs lower than stainless steel alternatives.
