Diamond Eye Cat-Back Exhaust Upgrade for GM 6.6L Duramax LBZ

Upgrade your 2006-2007 GM 6.6L Duramax LBZ with the Diamond Eye 5-inch Aluminized Cat-Back No Tip Exhaust with Turbo Direct Pipe! The 5-inch aluminized cat-back design enhances performance all while resisting the damaging effects of both rust and corrosion for long-lasting durability. At its core is the Diamond Eye muffler, constructed from stainless steel with a perforated core. This muffler produces a deep, aggressive tone that complements the power of your Duramax without being overly loud. It also minimizes exhaust interior drone, ensuring a comfortable driving experience when you're cruising at highway speeds. What's more, the exhaust's no-tip design allows for user customization, letting you add a tip that matches your style or leave it bare for a clean and functional look.

Included Turbo Direct Pipe

A standout feature of this kit is the included turbo direct pipe that replaces the restrictive factory unit with something much more effective. With CNC-machined end-forms for a precise fit and mandrel-bent tubing for smooth, unrestricted flow, this pipe optimizes the exhaust path right from the turbocharger. The pipe is also wrapped with a thermal-resistant covering, reducing exhaust gas temperatures (EGTs) by up to 150 degrees compared to the factory unit. This improvement protects your engine under load, particularly during towing or heavy-duty use.

Mandrel-Bent Tubing & Simple Installation

Diamond eye engineered their Aluminized Exhaust System with smooth mandrel bends which maximize exhaust flow, reduce backpressure and improve overall engine efficiency. These tweaks help lower EGTs, increase fuel economy, and provide slight gains in both horsepower and torque each time you hop on the accelerator. You may also feel a slight boost in throttle response which helps makes your truck feel more responsive, adding more enjoyment to your driving experience. Better yet, the system is made for a direct bolt-on installation and includes all necessary clamps and hardware. It utilizes OEM hangers for a secure fit, making installation straightforward for DIY enthusiasts or professional mechanics.
