Diamond Eye KIT 4in DPF-BACK Single SS 16-17 Chevrolet 6.6L Duramax 2500/3500

This is the Diamond Eye Performance 4-inch DPF-Back Single Exhaust Kit, part number K4166S. What you get in this kit is the stainless steel muffler and the necessary exhaust tubing to connect it to your truck's existing Diesel Particulate Filter (DPF) outlet. This kit is specifically made for 2016 and 2017 Chevrolet 2500 and 3500 trucks equipped with the 6.6L Duramax diesel engine.

This DPF-back system is designed to replace the factory muffler and tailpipe section behind the DPF. By using a larger diameter 4-inch stainless steel muffler, it can help improve exhaust flow compared to the stock setup. Stainless steel is a good choice for exhaust components because it holds up well against corrosion and the high temperatures exhaust gases produce. The single exit configuration keeps the look clean and straightforward.

When installing this kit, you'll be working with components that are designed to bolt up to your truck's factory DPF outlet. This means no welding is typically required for the main exhaust routing. Remember that this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details on mounting and any hardware that might be needed beyond what's included in the kit.
