Product Details

The Diamond Eye K3120S is a complete 3-inch cat-back single exhaust system engineered specifically for 2014 Chevrolet Silverado and GMC Sierra 1500 trucks equipped with 4.8L or 5.3L V8 engines. This performance exhaust system replaces the restrictive factory exhaust from the catalytic converter back, delivering improved exhaust flow for enhanced horsepower, torque, and fuel economy.

Key Features:

  • Constructed from durable 409 stainless steel for long-lasting corrosion resistance
  • 3-inch diameter mandrel-bent tubing ensures maximum exhaust flow and reduced backpressure
  • CNC mandrel-bent components provide smooth, unrestricted bends that optimize performance
  • Single side exit configuration with polished stainless steel tip included
  • Complete bolt-on kit includes all necessary hardware, clamps, and hangers for installation
  • Manufactured in the USA at Diamond Eye's state-of-the-art facility in Oregon
  • Engineered to work with factory mounting points for hassle-free installation

This system delivers a deeper, more aggressive exhaust tone compared to stock while maintaining reasonable interior sound levels. The mandrel-bent construction eliminates the crimped bends found in factory exhaust systems, allowing exhaust gases to exit more efficiently. The result is measurable gains in low-end torque and horsepower, improved throttle response, and potential fuel economy benefits. The 409 stainless steel construction offers excellent durability and rust resistance at a more affordable price point than premium 304 stainless systems.
