What is a DPF-back exhaust system?

A DPF-back exhaust system replaces the factory exhaust components starting from the Diesel Particulate Filter (DPF) and extending to the rear of the vehicle. It allows for a more direct exhaust gas path after the emissions control device.

What are the benefits of aluminized steel construction?

Aluminized steel offers good corrosion resistance for exhaust components at a more accessible price point than stainless steel. It provides a durable option for many vehicle applications.

Is this exhaust system legal in all states?

No, this exhaust system is not CARB approved and cannot be shipped to California due to emissions regulations. Always check your local and state emissions laws before purchasing and installing aftermarket exhaust components.

Product Details

This 4-inch aluminized DPF-back dual exhaust kit from Diamond Eye Performance is built for your 2011-2015 Chevrolet Silverado 2500 HD or 3500 HD, and also fits the 2011-2015 GMC Sierra 2500 HD and 3500 HD. The system replaces the factory Diesel Particulate Filter (DPF) back, allowing for a more direct path for exhaust gases to exit the vehicle. This can lead to a more efficient flow compared to the stock setup.

Diamond Eye uses CNC mandrel bending to create the tubing for this kit. Mandrel bending ensures that the pipe's diameter stays consistent throughout the bend, which is crucial for maintaining smooth exhaust flow and preventing restrictions. The aluminized steel construction offers a good balance of durability and cost-effectiveness for this type of exhaust system. This kit is designed as a direct bolt-on replacement for the factory exhaust system from the DPF back, simplifying the installation process.

This kit is designed to work with your truck's existing DPF. It's important to note that this system is not CARB approved and cannot be shipped to California. If you're looking to change the sound and flow characteristics of your Duramax diesel's exhaust, this DPF-back dual kit is a solid option.
