Product Details

The Diamond Eye K4124S is a complete 4-inch turbo-back exhaust system engineered for 2006-2007.5 Chevrolet and GMC 2500/3500 trucks equipped with the 6.6L Duramax diesel engine. This system fits all cab and bed length configurations, providing a universal solution for these model years.

Key Features:

  • 4-inch diameter mandrel-bent 409 stainless steel construction for maximum exhaust flow and durability
  • Turbo-back design replaces restrictive factory exhaust from turbo outlet to tailpipe
  • Precision CNC mandrel bending ensures smooth bends without crimping or flow restrictions
  • 409 stainless steel offers excellent corrosion resistance at an economical price point
  • Universal fit for all 2006-2007.5 Duramax cab and bed configurations (regular, extended, crew cab with short or long bed)
  • Bolt-on installation with factory-style hangers and hardware included

Upgrading to a 4-inch exhaust system reduces exhaust gas temperatures, decreases backpressure, and can improve fuel economy and horsepower on these workhorse diesel trucks. The mandrel-bent construction maintains consistent pipe diameter through all bends, unlike crush-bent systems that restrict flow. Diamond Eye's 409 stainless steel material provides long-lasting protection against rust and corrosion while remaining budget-friendly compared to premium T304 stainless options.

I ordered my shifter last night and I got a tracking number today, shipment seems to be speedy and arrive in 3 days with standard shipping.. cheapest price I can find anywhere!

Good Price, easy online browsing.

Great pricing, Great service, and Great variety !!! I highly reccomend this site!!!

Quick and easy online shopping and check out. Shipping took long because it had to come from a manufacturer. Also considering the part was small shipping costs seemed high. Everything arrived in order though and part seems just right.

very good

Autoplicity was a great place to shop. By far the lowest price on the rack that I purchased. Fast shipping and overall very satisfied.<br><br>
