Product Details

The Diamond Eye K4214S-RP is a complete 4-inch turbo-back exhaust system engineered specifically for 1994-2002 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 second-generation Dodge diesel trucks.

Key Features:

  • 4-inch mandrel-bent 409 stainless steel construction for maximum flow and durability
  • Turbo-back design replaces restrictive factory exhaust from turbocharger to tailpipe
  • Precision-bent tubing maintains consistent diameter throughout for optimal exhaust flow
  • 409 stainless steel offers excellent corrosion resistance and longevity
  • Designed to fit all cab configurations (Regular, Quad, Club) and bed lengths
  • Mandrel-bent construction prevents crushing and maintains pipe diameter at bends
  • Direct bolt-on installation with all necessary hardware included

Upgrading to a 4-inch exhaust system significantly reduces exhaust gas temperatures (EGTs), improves turbo spool-up, and unlocks additional horsepower and torque from your Cummins diesel. The larger diameter tubing eliminates backpressure restrictions, allowing your engine to breathe more efficiently whether stock or modified. Diamond Eye's mandrel-bending process ensures smooth transitions at every bend, maximizing exhaust velocity and scavenging efficiency.

This system is ideal for truck owners looking to enhance performance, reduce turbo lag, and achieve that distinctive diesel exhaust tone. The 409 stainless steel construction provides years of reliable service while resisting rust and corrosion far better than aluminized steel alternatives.

Great experience! I placed my order on Sunday and my programmer arrived on Thursday - with ground shipping. I unpacked the programmer and it functioned exactly as I had hoped. I will definitely consider purchasing from Autoplicity again!

Competitive prices but wish there were vehicle application lists for parts.
