Diamond Eye KIT 4in DPF-BACKSGLTD SS 11-13 Chevy/GMC 6.6L Duramax 2500/3500

This 4-inch diameter DPF-back exhaust system from Diamond Eye Performance is constructed from T409 stainless steel, a material chosen for its good resistance to corrosion and heat, making it a solid choice for the demanding environment under your truck. It's designed to replace the factory exhaust system from the Diesel Particulate Filter (DPF) rearward, offering a more direct path for exhaust gases. This can lead to improved exhaust flow, which often translates to a deeper, more aggressive exhaust tone and potentially a slight increase in throttle response.

The kit is specifically made for 2011 through 2013 Chevrolet and GMC 2500 and 3500 trucks equipped with the 6.6L Duramax diesel engine. Installation typically involves removing the stock muffler and tailpipe and bolting in the new components. Because it's a DPF-back system, it works with your truck's existing emissions control equipment, meaning it doesn't alter the DPF itself. Diamond Eye Performance is known for making well-built exhaust components, and this kit continues that reputation with its durable stainless steel construction and direct-fit design.

When installing this system, you'll want to ensure you have the necessary tools for unbolting the factory exhaust and securing the new pipes. While this system is designed for improved flow and sound, it's important to note that it is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to the manufacturer's installation guide for specific instructions and torque specifications to ensure a proper and safe installation.
