Diamond Eye KIT 5in Catback Single 409 SS: 2006-2007.5 CHEVY/GMC 6.6L DURAMAX 2500/3500

If you're looking to get more out of your 2006-2007.5 Chevrolet or GMC 6.6L Duramax truck, a cat-back exhaust system is a solid upgrade. This kit from Diamond Eye Performance replaces your factory exhaust from the catalytic converter back, featuring a larger 5-inch diameter for better flow. It's designed to fit all cab and bed lengths for the specified models, making it a straightforward installation for your 2500 or 3500 HD.

Diamond Eye builds this system using 409 stainless steel, which offers good resistance to corrosion and heat, especially important for a diesel exhaust. They use CNC mandrel bending to ensure consistent tube diameter throughout the system, which helps maintain smooth exhaust gas flow and can contribute to improved performance and a deeper exhaust note. The single muffler design is part of what gives this system its specific sound profile.

This kit includes everything needed to replace your stock exhaust system from the catalytic converter back. You'll get the main exhaust pipes, the muffler, and any necessary hangers or clamps for a complete installation. Having a well-flowing exhaust like this can help your Duramax engine breathe easier, potentially leading to better throttle response and efficiency.
