Product Details

The Diamond Eye K4257S is a complete 4-inch DPF-back single exhaust system engineered specifically for 2014 Dodge Ram 2500 Mega Cab Short Box trucks equipped with the 6.7L Cummins diesel engine. This system is constructed from durable 409 stainless steel, offering excellent corrosion resistance and longevity.

Key Features:

  • 4-inch mandrel-bent tubing throughout for maximum exhaust flow and reduced backpressure
  • 409 stainless steel construction resists rust and corrosion
  • DPF-back design retains factory emissions equipment for street legality
  • Single exit configuration optimized for Mega Cab Short Box models
  • Precision-engineered using CNC mandrel bending for consistent fitment
  • Direct bolt-on installation with all necessary hardware included

This exhaust system improves exhaust flow over the restrictive factory system, helping to increase horsepower and torque while enhancing throttle response. The mandrel-bent construction maintains consistent tubing diameter throughout each bend, eliminating the restrictions found in crush-bent systems. Designed and manufactured in the USA by Diamond Eye Manufacturing, this system is backed by their commitment to quality and precision fitment.

Competitve prices!

Shopping experience excellent (so far)!

Your competitive pricing won my business through the internet and I wasn't disappointed. The price was great ( about 1/2 MSRP) and item was shipped very quickly. No backorder problems here! I was impressed with the quality of my H pipe and with the packaging.

After having trouble completing the payment process through Amazon, I was able to complete my payment information directly on the Autoplicty website and submit the order quickly. The process was easy and fast. They had the best overall price (item plus shipping) I could find on the net. The item was shipped promptly and arrived in great condition. A quality merchant all the way around.

did not have accurate pictures for product so have to go off of part number only product came on time and as expected at good price

I like how fast they ship and they have great prices. I will shop Autoplicity again. Thanks Guys

gave me a 20% off shipping code but didn't give me a place to use it

The sales/service team were very helpful and they had the cheapest price for an air filter that I could find. I will definitely shop here again!

Customer service was very helpful. Great prices. Quick shipping.
