Diamond Eye KIT 4in DPF-BACK Single AL: 11-12 CHEVY 6.6L 2500/350

This Diamond Eye Performance DPF-back exhaust kit gives your 2011-2013 Chevrolet Silverado 2500 HD or 3500 HD, and your 2011-2012 GMC Sierra 2500 HD or 3500 HD, a straightforward upgrade for your exhaust system. It's designed to replace the factory exhaust from the Diesel Particulate Filter (DPF) back, offering a simpler installation and a noticeable change in sound and exhaust flow. The kit includes the necessary components to get your truck's exhaust flowing more freely.

Built with aluminized steel, this system is well-made to handle the rigors of daily driving and various weather conditions. Diamond Eye uses CNC mandrel bending to ensure consistent tube diameter throughout the bends, which helps maintain smooth exhaust gas flow. This attention to detail in fabrication means you get a system that's not only functional but also built to last. The 4-inch diameter tubing is a popular size for these trucks, providing a good balance between improved exhaust flow and a deep, satisfying tone without being overly aggressive.

This kit is a popular choice for owners looking to get a bit more sound and performance out of their Duramax diesel engine. It's designed as a direct fit for the specified cab and bed lengths, simplifying the installation process. Remember, this system is not CARB approved and cannot be shipped to California.
