Product Details

The Diamond Eye K4212A-RP is a complete 4-inch aluminized 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 diameter aluminized steel construction for durability and corrosion resistance
  • Mandrel-bent tubing maintains consistent pipe diameter throughout bends for optimal exhaust flow
  • Turbo-back design maximizes performance gains by reducing backpressure from the turbocharger to the tailpipe
  • Complete bolt-on system includes all necessary pipes, clamps, and hardware for installation
  • Universal fit accommodates all 1994-2002 Dodge Ram 2500/3500 cab and bed configurations
  • Precision CNC mandrel-bent components ensure proper fitment and maximum flow efficiency

This exhaust system delivers improved exhaust gas temperatures, increased horsepower and torque, and enhanced throttle response. The aluminized steel construction provides excellent protection against road salt and corrosion while offering an economical alternative to stainless steel. Diamond Eye's mandrel bending process ensures smooth transitions and unrestricted flow throughout the entire exhaust path, making this system ideal for both stock and modified Cummins diesel engines.

So far so good, just doesn't say for sure what it fits.

You had what we needed at an affordable price.

It was great, you had excellent prices, and the 2nd day shipping was better than most competitors.

This was the cheapest price and no one came close but delivery took forever.

Live inventory is a great feature. Easy ordering.

Easy to navigate

Easy!

Great

Good first shopping experience on your web site.

Nice Store. Best price on the product I was looking for. Received my item within a week. But online order status wasn't updated until the day I received the item. I was ready to call the store to find out if something is wrong with my order. This part could be improved. Otherwise I'm happy and definitely be back in the future.

Easy going

Sounds great bolted right on to my 2001 cummins. The only hard part was getting my old exhaust Off. The instructions were pretty vague, so i just had to just figure out which clamps go where. My truck is a single cab long bed so I had an extra piece of pipe left over. The instructions don't indicate anything about which pieces are used for which truck body style. Other than that it is amazing. And pretty loud. But not in the cab surprisingly.
