Diamond Eye KIT 5in Catback MRP Single w/ TDP AL 06-07 Chevy/GMC 6.6L Duramax 2500/3500

If you're looking to get more out of your 2006-2007 Chevrolet Silverado or GMC Sierra with the 6.6L Duramax engine, this 5-inch cat-back exhaust system from Diamond Eye is a solid option. It's designed to replace your factory exhaust from the catalytic converter back, aiming to improve exhaust flow and potentially give your truck a deeper tone.

Diamond Eye uses CNC mandrel bending to shape the aluminized steel tubing, which helps maintain consistent diameter throughout the bends. This ensures exhaust gases can exit the engine more freely compared to restrictive factory systems. The 5-inch diameter is larger than stock, allowing for better flow, especially important for the 6.6L Duramax engine. This kit is made from aluminized steel, offering a good balance of corrosion resistance and affordability.

This kit is designed as a direct replacement for your stock exhaust system, meaning it should fit right onto your 2006 or 2007 Silverado or Sierra 2500 HD or 3500, regardless of cab and bed length. While it's designed for improved flow, remember that exhaust modifications can affect emissions and may not be legal in all areas. Always check your local regulations before installing.
