Diamond Eye KIT 4in DPF-BACKSGLTD AL 11-15 Chevy/GMC 6.6L Duramax 2500/3500

This is a 4-inch DPF-back exhaust system kit from Diamond Eye Performance, designed specifically for 2011-2015 Chevrolet and GMC 2500/3500 trucks equipped with the 6.6L Duramax diesel engine. This kit replaces the factory exhaust system from the Diesel Particulate Filter (DPF) back, featuring a single turn-down tip. It's constructed from aluminized steel, offering a good balance of durability and cost-effectiveness for your truck.

Diamond Eye uses CNC mandrel bending to ensure consistent tube diameter throughout the exhaust path. This process helps maintain smooth airflow, which can lead to a slightly improved exhaust note and better flow compared to stock. The aluminized steel construction provides resistance to corrosion, making it a solid option for everyday use. This kit is designed to fit right onto your existing DPF, simplifying the installation process.

Please note that this exhaust system is not CARB approved and cannot be shipped to California. If you're looking to replace your factory exhaust from the DPF back and want a straightforward upgrade, this Diamond Eye kit is a popular choice.
