Diamond Eye KIT 4in Catback MRP Single w/ TDP SS 06-07 Chevy/GMC 6.6L Duramax 2500/3500

Diamond Eye Performance is known for its modern manufacturing approach, utilizing CNC mandrel bending machines to create high-quality exhaust components. This 4-inch cat-back exhaust system is specifically built for your 2006-2007 Chevrolet Silverado 2500 HD or 3500, and GMC Sierra 2500 HD or 3500 equipped with the 6.6L Duramax LBZ engine. It replaces the factory exhaust from the catalytic converter back, aiming to improve exhaust flow and potentially alter the exhaust note.

Constructed from stainless steel, this system is designed to resist corrosion, especially important for trucks that see varied weather conditions. The 4-inch diameter tubing is mandrel-bent, which helps maintain the tube's inner diameter throughout the bend, allowing for smoother exhaust gas passage compared to crush bends. This can lead to better performance and a more aggressive sound profile. The kit includes the necessary components for installation, designed as a direct replacement for the stock system.

This cat-back system is a solid option if you're looking to upgrade the exhaust on your Duramax truck. Diamond Eye has a dedicated research and development center focused on creating systems that keep pace with the aftermarket, and their extensive inventory and efficient shipping methods aim to get you your parts quickly.
