Product Details

The Diamond Eye Manufacturing 362007 is a 4-inch aluminized steel catalytic-converter-back performance exhaust kit engineered for 2001 through early 2007 Chevrolet and GMC Silverado/Sierra 2500 and 3500 HD trucks equipped with the 6.6L Duramax diesel engine (LB7, LLY, and LBZ). The kit is designed to fit all cab and bed length configurations, making it a true direct-fit upgrade with no cutting or welding required.

Constructed using CNC mandrel-bent aluminized steel tubing, this exhaust system maintains consistent inner diameter throughout every bend, eliminating the flow restrictions that plague crush-bent alternatives. The result is reduced exhaust backpressure, which translates directly into lower exhaust gas temperatures (EGTs), improved throttle response, and gains in horsepower and torque.

Key Features:

  • 4-inch diameter aluminized steel mandrel-bent tubing for maximum exhaust flow
  • Catalytic converter-back configuration — retains factory catalytic converter
  • Fits all cab and bed lengths on 2001–Early 2007 Chevy/GMC 2500/3500 HD
  • Compatible with 6.6L Duramax LB7, LLY, and LBZ diesel engines
  • Utilizes OEM-style hangers for a bolt-on, no-drill installation
  • Aluminized steel construction for durability and corrosion resistance
  • Aggressive exhaust note with improved engine breathing
  • 1-Year Limited Warranty on aluminized steel kits

This exhaust kit is not legal for sale or use in California on any pollution-controlled motor vehicle. Designed for off-road or racing use where permitted by law. Diamond Eye Manufacturing produces all exhaust components using precision CNC mandrel-bending equipment, ensuring consistent quality and fitment straight out of the box.

Great prices. Fast shipping. Huge inventory.

Great product. Fast shipping. Great and easy to use website! The air filter I purchased <br>From them cost $20 less than it was priced for at other competitors! I am very happy with the price.

great chair for pool table area or any man cave

very happy with Autoplicity.com, good price and they had the shocks I needed, fast shipping. I will be doing more shopping at autoplicity.com. Thanks Mark

I needed two fairly expensive parts for a project. Naturally, I shopped everywhere before deciding on where to purchase them. Autoplicity had the best price on the carburetor. I continued shopping around for the alternator, and ended up right back at the Autoplicity website, because they beat everyone else on that price also! And I don't mean by a few dollars! HUGE savings! Thanks Autoplicity! In the words of Arnold, "I'll be back!"

Fast shipping and saved $60 on a $399 item. However you have to verify your part #'s with the vendor. The part discription on autoplicity sometimes is not what you get. I ordered an item that said it was an O2 plug and bung but when it showed up it was just the bung plug sold separate and customer service basically said it was my bad for not checking for a more accurate discription on the Allstar web site.

Item arrived promptly (4 days after order), price was good and item was as described.

ordered a K&N air filter, pretty simple. good price, timely shipping.

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!
