Product Details

The Diamond Eye Manufacturing K4209A is a complete 4-inch aluminized steel turbo-back exhaust system designed specifically for 1989-1993 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine. This system fits all cab and bed length configurations, providing a direct-fit solution for improved exhaust flow and performance.

Key Features:

  • 4-inch diameter aluminized steel construction for durability and corrosion resistance
  • Turbo-back design maximizes exhaust flow from turbo to tailpipe
  • Mandrel-bent tubing maintains consistent diameter through bends for optimal flow
  • Universal fitment for all 1989-1993 Dodge Ram 2500/3500 cab and bed configurations
  • Complete system includes all necessary pipes, clamps, and hardware for installation
  • Engineered to reduce exhaust gas temperatures (EGT) and backpressure

This exhaust system is manufactured using precision CNC mandrel bending technology, ensuring consistent quality and proper fitment. The aluminized steel construction offers excellent value while providing long-lasting protection against rust and corrosion. By reducing exhaust restriction, this system helps improve throttle response, fuel economy, and overall engine performance in early first-generation Cummins-powered Dodge trucks.
