Diamond Eye Manufacturing 361040 Performance Exhaust Kit 2007.5-2010 Chevy/GMC 6.6L Duramax Diesel

The Diamond Eye Manufacturing 361040 is a performance exhaust system engineered specifically for 2007.5–2010 Chevrolet and GMC 2500/3500 trucks equipped with the 6.6L Duramax diesel engine. Designed to replace restrictive factory exhaust components, this kit is compatible with all cab and bed length configurations, making it a versatile upgrade for both work trucks and daily drivers.

Diamond Eye fabricates this system using mandrel-bent tubing to ensure smooth, unrestricted exhaust flow through every bend — eliminating the crimping and flow restrictions common with press-bent alternatives. The result is improved exhaust scavenging, reduced backpressure, and a noticeable gain in engine efficiency and exhaust note.

Key Features:

• Mandrel-bent tubing for maximum flow and minimal restriction
• Available in aluminized steel construction for corrosion resistance and durability
• Designed to fit all cab and bed length combinations on 2500/3500 platforms
• Direct bolt-on installation — no cutting or welding required
• Precision CNC-bent components for consistent, repeatable fitment
• Engineered to work with or without a diesel particulate filter (DPF) delete configuration

Diamond Eye Manufacturing produces all components at their Oregon facility using CNC mandrel bending equipment, ensuring tight tolerances and a factory-quality fit. This exhaust system is an ideal choice for Duramax owners seeking improved performance, a more aggressive exhaust tone, and long-lasting durability.
