Diamond Eye K3424A 3.5" Cat-Back Exhaust System Aluminized Steel

The Diamond Eye K3424A is a complete 3.5-inch diameter cat-back exhaust system designed for 2010-2014 Toyota Tundra trucks equipped with the 5.7L V8 engine. This single-exit exhaust system is constructed from durable aluminized steel for excellent corrosion resistance and long-lasting performance.

Key Features:

• 3.5-inch mandrel-bent tubing for maximum exhaust flow and reduced backpressure
• Cat-back design replaces exhaust from catalytic converter to tailpipe
• Aluminized steel construction provides rust resistance at an economical price point
• Single side exit configuration
• Precision CNC mandrel bending ensures consistent tube diameter throughout bends
• Direct bolt-on installation with all necessary hardware included

Diamond Eye's mandrel-bent tubing maintains constant inner diameter through curves, unlike crush-bent systems, allowing exhaust gases to flow more freely. This results in improved horsepower, torque, and throttle response while delivering a deeper, more aggressive exhaust tone. The aluminized steel material offers a cost-effective balance between durability and performance for truck owners seeking exhaust upgrades.
