Diamond Eye KIT 4in Catback MRP Single w/ TDP SS 04-05 Chevy/GMC 6.6L Duramax 2500/3500

If you're looking to get more out of your 2004-2005 Chevrolet Silverado 2500 HD with the 6.6L Duramax engine, this 4-inch stainless steel cat-back exhaust system from Diamond Eye Performance is a solid option. It replaces the factory exhaust from the catalytic converter back, aiming to improve exhaust flow and give your truck a deeper, more robust sound.

Diamond Eye Performance uses CNC mandrel bending to create smooth, consistent bends in the tubing. This process helps maintain the pipe's diameter through the bends, which is crucial for efficient exhaust gas flow. The entire system is constructed from stainless steel, offering good resistance to corrosion and making it a durable choice for your truck, especially if you encounter harsh weather or road conditions. This kit is designed as a direct replacement for your factory system, meaning it should bolt up without needing extensive modifications.

This kit includes all the necessary components for installation, designed to fit all cab and bed lengths for the specified models. While this system is designed to improve exhaust flow, it's always a good idea to check local regulations regarding exhaust modifications.
