GM 6.6L Duramax LLY Exhaust Upgrade Improves Sound and Performance

Give your 2004.5-2005 GM 2500HD/3500HD a major boost in sound and performance with the Diamond Eye 4in Aluminized Cat-Back Single Exit No Tip Exhaust! One of the major downfalls of your truck's factory exhaust is its restrictive design. This not only mutes the sound of your 6.6L Duramax but also allows for an increase in back pressure which can significantly hinder engine performance. Fortunately, Diamond Eye understands this issues which is why they crafted their exhaust using smooth mandrel bends in the tubing to ensure smooth and unrestricted airflow. Th result is slight gains in horsepower and torque, improved throttle response, and better fuel economy across the entire RPM range. You'll also benefit from the lower exhaust gas temperatures (EGTs) to help protect your engine during towing or other high-demand tasks. What's more, the no-tip design keeps the exhaust clean and simple, allowing you to customize the look with your choice of tip or leave it bare for a rugged finish.

Diamond Eye Muffler with Aluminized Steel Construction

Constructed from durable aluminized steel, this exhaust system resists rust and corrosion, making it a practical choice for daily use and tough environments. The system also features a stainless steel muffler with a perforated core, engineered to deliver optimal airflow and a balanced exhaust tone. This muffler gives your Duramax a deep and aggressive rumble that highlights the power of your heavy-duty diesel engine. It strikes the perfect balance between assertive and refined, making it ideal for everyday driving or heavy-duty use. Additionally, the muffler reduces exhaust interior drone, ensuring a more comfortable cabin experience during long road trips. And top things off, installation is incredibly simple as this system installs directly in place of your truck's stock exhaust to make for a simple and straightforward process you can complete at home.
