Diamond Eye KIT 4in Catback DUAL SS: 2006-2007.5 CHEVY/GMC 6.6L 2500/3500

Diamond Eye Performance is known for its modern manufacturing approach, investing heavily in CNC mandrel bending machines to produce high-quality exhaust components. This 4-inch dual stainless steel cat-back exhaust system, part number K4124S, is built for your 2006-2007.5 Chevrolet Silverado 2500 HD or 3500, or its GMC Sierra equivalent, equipped with the 6.6L Duramax engine. It's designed to fit all cab and bed lengths, ensuring a straightforward installation for your truck.

This system utilizes 409 stainless steel, which offers good corrosion resistance for a long service life. The 4-inch diameter tubing and dual outlet design are intended to improve exhaust flow compared to the factory setup. Mandrel bending ensures consistent tube diameter throughout the bends, which helps maintain smooth airflow and prevent restrictions. Diamond Eye's commitment to research and development, combined with experienced staff, means this system is crafted with attention to detail to meet the demands of the performance aftermarket.

When installing this cat-back system, you can expect a noticeable change in exhaust tone and potentially improved throttle response due to the increased exhaust gas velocity. The kit includes all necessary components for installation as a cat-back system, meaning it replaces the exhaust from the catalytic converter back. Refer to the manufacturer's installation instructions for specific details regarding the mounting hardware and any required tools.
