Product Details

The Diamond Eye K4124A is a complete 4-inch aluminized steel turbo-back exhaust system engineered specifically for 2006-2007.5 Chevrolet and GMC 2500/3500 HD trucks equipped with the 6.6L Duramax diesel engine. This exhaust system is designed to fit all cab and bed length configurations, providing a universal solution for these popular heavy-duty trucks.

Key Features:

  • 4-inch diameter mandrel-bent aluminized steel construction for maximum exhaust flow and durability
  • Turbo-back design replaces restrictive factory exhaust from turbo outlet to tailpipe
  • Precision mandrel bending maintains consistent tube diameter throughout bends for optimal flow
  • Aluminized steel construction provides excellent corrosion resistance at an economical price point
  • Universal fitment accommodates all cab styles (regular, extended, crew) and bed lengths
  • Complete bolt-on installation with all necessary hardware and clamps included

Upgrading to a 4-inch exhaust system reduces exhaust gas temperatures, decreases backpressure, and helps unlock additional horsepower and torque from your Duramax engine. The larger diameter tubing allows the turbocharger to spool more efficiently while improving fuel economy under normal driving conditions. Diamond Eye's mandrel-bent construction ensures smooth exhaust flow without the restrictions found in crush-bent systems.

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Quick and easy

Ordering is easy waiting on shipment to check accurate item??

better than a lot of online shopping i've done, make that most online shopping i've done and thanks for the 10% shipping discount

I went through the Amazon payment option and it was a hassle.

So fast and easy once I found what I was looking for!

Very easy and quick ordering process, so far so good. Completely satisfied with the product and the speed of shipment. Would gladly do business again with Autoplicity.

Excellent shipping received very fast and well packaged

Beat price. Super fast processing and shipping. Will shop there again.

Great price for the item, almost half off. Good website for auto parts

Fast

I shopped around a little first and Autoplicity had the best price on a wideband sensor and gauge. When I needed a fuel pressure regulator too, I found their price was the best so I ordered both from them. Great prices and fast deliver!

Pretty simple and easy to use
