Single-Exit Aluminized Exhaust Upgrade for 6.6L Duramax

The Diamond Eye 4in Aluminized Cat-Back Singe Exit No Tip Exhaust is engineered to improve exhaust flow, enhance sound, and boost efficiency, making it a reliable and cost-effective upgrade for your 2006-2007 GM 6.6L Duramax. Constructed from aluminized steel, this exhaust system offers impressive durability and rust resistance at an affordable price point. The aluminized coating protects the steel from corrosion, making it suitable for most driving conditions. While stainless steel provides superior resistance to rust, particularly in harsh environments like coastal areas or places where road salt is prevalent, aluminized steel remains a dependable choice for drivers seeking a balance of performance and value. Your truck will also benefit from the 4-inch mandrel-bent tubing which ensures smooth, unrestricted airflow, reducing backpressure and maximizing engine efficiency. These improvements lead to slight gains in both horsepower and torque, improved throttle response, and better fuel economy at highway speeds.

Diamond Eye Muffler & Simple Install

At the heart of the system is the Diamond Eye muffler, crafted with a perforated core and stainless steel construction. This muffler enhances airflow and delivers a deep, aggressive exhaust tone that complements the power of your Duramax without being overly loud. The design also reduces exhaust interior noise, ensuring a more comfortable ride whether you’re towing, hauling, or simply cruising through town. Better yet, installation is simple and hassle-free, with the system designed to utilize your truck’s OEM hangers for a secure fit. All necessary clamps and hardware are included, making it easy for both DIY enthusiasts and professional mechanics to install.
