Diamond Eye K3116S 3" Cat Back Single Exhaust System 409 Stainless Steel

The Diamond Eye K3116S is a complete 3-inch diameter cat-back single exhaust system engineered specifically for 2009-2013 Chevrolet Silverado 1500 trucks equipped with 4.8L or 5.3L V8 engines. This system is constructed from durable 409 stainless steel, offering excellent corrosion resistance and longevity compared to aluminized steel systems.

Key Features:

• 3-inch mandrel-bent tubing for maximum exhaust flow and reduced backpressure
• 409 stainless steel construction resists rust and corrosion
• Single side exit configuration for clean, OEM-style appearance
• Complete cat-back system includes all necessary pipes, muffler, and hardware
• Precision CNC mandrel bending ensures consistent tube diameter throughout bends
• Direct bolt-on installation with no cutting or welding required

This exhaust system delivers improved exhaust flow over the restrictive factory system, resulting in modest horsepower and torque gains while producing a deeper, more aggressive exhaust tone. The mandrel-bent construction maintains the full 3-inch inner diameter through all bends, eliminating the flow restrictions found in crush-bent exhaust systems. All components are manufactured to exacting tolerances for proper fitment and professional results.
