Diamond Eye KIT 4in Catback Single AL CHEVY/GMC 6.6L 2500/3500 2006-2007.5

This 4-inch aluminized cat-back exhaust system is built using CNC mandrel bending, a process that ensures consistent tube diameter throughout bends. This helps the exhaust gases flow more freely than a stock system, which can make a noticeable difference in how your 6.6L Duramax engine performs. The aluminized steel construction offers good corrosion resistance for everyday driving conditions.

Diamond Eye Performance builds this system specifically for the 2006-2007.5 Chevrolet Silverado 2500 HD and 3500, as well as the 2006 GMC Sierra 2500 HD and 3500. It's designed as a direct replacement for your factory exhaust, meaning it fits right without needing modifications. The single-exit design keeps things straightforward while still improving exhaust flow.
