Give your GM 2500HD/3500HD Impressive Sound & Performance with Diamond Eye

One of the easiest ways to add more aggression and capability to your 2006-2007 GM 2500HD/3500HD is with an aftermarket exhaust system! Specifically, the Diamond Eye 5in Aluminized Cat-Back Single Exit No Tip Exhaust offers the ultimate upgrade as it works to optimize your 6.6L Duramax by replacing the restrictive factory exhaust with something much more effective. The 5-inch aluminized steel tubing provides a significant upgrade in durability and performance. The aluminized coating resists rust and corrosion, making it a practical choice for harsh, wet environments. What's more, the mandrel-bent construction ensures smooth, unrestricted airflow, reducing backpressure and lowering exhaust gas temperatures (EGTs) when you're behind the wheel. These improvements contribute to slight gains in horsepower and torque, improved throttle response, and better fuel economy—practical benefits for any truck owner, whether you’re towing, hauling, or simply enjoying the drive.

Cat-Back Configuration & Simple Installation

The cat-back design replaces the exhaust from the catalytic converter to the tailpipe, allowing for better flow and efficiency while maintaining emissions compliance. At the heart of the system is a Diamond Eye muffler constructed from stainless steel with a perforated core. This muffler is designed to balance performance and sound, giving your truck a deep, aggressive rumble that highlights the power of the Duramax engine. It’s assertive without being overpowering, and it effectively reduces interior drone for a more comfortable ride on long trips or daily commutes. When it comes to installation, the exhaust bolts directly in place of your truck's existing system using the included hardware and instructions provided by Diamond Eye.
