Diamond Eye KIT 4in DPF-BACK DUAL SS: CHEVY 2011-2015 2500/3500

If you're looking to upgrade the exhaust on your 2011-2015 Chevrolet Silverado 2500 HD or 3500 HD with the 6.6L Duramax engine, this 4-inch stainless steel DPF back dual exhaust kit from Diamond Eye Performance is a solid option. This kit is designed to replace the factory exhaust system from the Diesel Particulate Filter (DPF) back, giving your truck a more aggressive sound and potentially improved exhaust flow.

Diamond Eye Performance uses CNC mandrel bending to ensure consistent tube diameters throughout the system, which helps maintain smooth airflow. The entire kit is constructed from stainless steel, offering good resistance to corrosion and ensuring it holds up well over time, especially on trucks that see regular use. This kit is a direct replacement for the factory system, meaning it's designed to fit right without requiring significant modifications during installation.

This DPF back dual exhaust system is a popular choice for Duramax owners looking for a noticeable change in their truck's exhaust note and appearance. While it's designed to work with the factory DPF, it's important to note that this system is not CARB approved and cannot be shipped to California. For installation, you'll typically be bolting this system up to the existing DPF outlet, making it a more straightforward job than a full turbo-back system.
