Diamond Eye K3420A 3.5 Inch Aluminized Cat-Back Single Exhaust System

The Diamond Eye K3420A is a 3.5-inch aluminized steel cat-back exhaust system featuring CNC mandrel-bent tubing that is resistant to rust and corrosion. This single-exit performance exhaust is designed to reduce backpressure and improve exhaust flow on 2007-2009 Toyota Tundra trucks equipped with the 5.7L gas engine.

Key Features:

• 3.5-inch mandrel-bent aluminized steel construction for durability
• Single side-exit configuration with universal fitment for all cab and bed lengths
• Universal design requires minor cutting to fit specific truck configurations; includes extension pipes for long bed models
• Complete kit includes all necessary clamps, hangers, and hardware for installation
• Aggressive exhaust note that wakes up under acceleration with minimal cabin drone
• Improves exhaust flow while maintaining backpressure for optimal performance

This performance exhaust system delivers a deeper, more aggressive sound without being excessively loud. The system is covered with a 1-year warranty against defects on materials and craftsmanship. Installation requires light to moderate mechanical skill, and some cutting and fitting is necessary to achieve proper fitment for your specific Tundra configuration.

Note: This exhaust system is not legal for sale or use in California on any pollution controlled motor vehicle. Stainless steel tip not included.
