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

If you're looking to get more out of your 2006-2007 Chevrolet Silverado 2500 HD with the 6.6L Duramax engine, this 4-inch stainless steel cat-back exhaust system from Diamond Eye Performance is a solid option. It's built using 409 stainless steel, which is known for its resistance to corrosion, meaning it should hold up well over time, even in varied weather conditions. The system is designed to replace your factory exhaust from the catalytic converter back, giving you a more direct path for exhaust gases to exit the vehicle.

Diamond Eye Performance uses CNC mandrel bending for their tubing. This process bends the pipe without collapsing the diameter, ensuring a consistent 4-inch inner diameter throughout the system. This smooth, uninterrupted flow helps exhaust gases escape more efficiently than the stock system, which can lead to a slightly improved throttle response and a deeper exhaust tone. The kit is designed as a direct replacement for your factory exhaust, making installation more straightforward. It's built to fit all cab and bed lengths for the specified 2006-2007.5 model years.

This cat-back system comes with everything needed for installation, including the necessary tubing and single muffler. Having a well-flowing exhaust is key for these powerful diesel trucks, and this stainless steel setup from Diamond Eye is built to last and perform.
