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

If you're looking to get a better sound and improved exhaust flow out of your 2006-2007 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the 6.6L Duramax engine, this 4-inch cat-back exhaust system from Diamond Eye is a solid option. This kit replaces the factory exhaust from the catalytic converter back, giving your truck a more aggressive tone and potentially freeing up some horsepower by letting the engine breathe easier.

Diamond Eye uses CNC mandrel bending to create smooth bends in the tubing, which helps maintain consistent exhaust gas velocity and reduces backpressure. This aluminized steel construction is chosen for its balance of durability and cost-effectiveness, offering good resistance to corrosion for everyday driving. The dual outlet design gives your truck a more muscular look from the rear.

This kit is designed to fit all cab and bed lengths for the specified 2006-2007.5 model years. While this system is designed as a direct bolt-on replacement, it's always a good idea to refer to the manufacturer's installation instructions for any specific details or hardware requirements.
