Product Details

The Diamond Eye K4211A is a complete 4-inch aluminized steel turbo-back exhaust system engineered specifically for 1989-1993 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine. This exhaust system fits all cab and bed length configurations, providing a universal solution for first-generation Cummins owners.

Key Features:

  • 4-inch mandrel-bent aluminized steel construction for maximum exhaust flow and durability
  • Turbo-back design replaces restrictive factory exhaust from turbo to tailpipe
  • Reduces exhaust gas temperatures (EGT) and improves engine performance
  • Increases horsepower and torque throughout the powerband
  • Improves fuel economy through reduced backpressure
  • Universal fitment for all 1989-1993 Dodge Ram Cummins cab and bed configurations
  • Mandrel-bent tubing maintains consistent diameter through bends for optimal flow
  • Aluminized steel construction provides excellent corrosion resistance

Diamond Eye Manufacturing utilizes precision CNC mandrel bending technology to ensure each component maintains exact specifications for proper fitment and maximum exhaust flow. The larger 4-inch diameter significantly reduces exhaust restriction compared to factory systems, allowing your Cummins diesel to breathe freely and perform at its best. This system is an essential upgrade for anyone looking to improve their first-generation Cummins performance and reliability.
