Beyond Just Sound: A Symphony of Performance and Precision:
This isn’t just an exhaust system; it’s a transformation. Kooks has meticulously designed this axle-back to not only enhance your Corvette’s auditory experience but also to optimize its performance. This system is engineered to significantly increase exhaust flow, reduce weight compared to the factory system, and dramatically increase volume output in loud mode. Feel the difference in throttle response and experience the exhilarating surge of extra horsepower and less weight.
Key Features & Benefits – Where Performance Meets Control:
- OEM-Style Dual-Mode Operation: Power When You Demand It: This system replicates the OEM dual-mode functionality. When driving under normal conditions, the valves remain closed, providing a refined, subdued tone. As you accelerate and exceed approximately 3500 RPM, the increasing vacuum pressure triggers the valves to open, unleashing the full, thunderous roar of the straight-pipe “loud mode.”
- Seamless OEM Integration & Optional On-Demand Manual Control: Designed for a perfect fit, this system seamlessly integrates with your factory vacuum lines, enabling automatic dual-mode operation. For those who demand complete control, it’s also fully compatible with “mild to wild” remote systems (sold separately), allowing you to instantly switch between loud and quiet modes at the touch of a button.
- Striking Aesthetics: A Visual Statement of Power: The eye-catching 4″ round quad matte carbon fiber tips add a touch of modern sophistication and aggression to your Corvette’s rear profile, making a bold visual statement wherever you go.
- Uncompromising Quality: Built to Last: Constructed from premium 304 stainless steel, this exhaust system is built to withstand the rigors of high-performance driving. Enjoy exceptional durability and corrosion resistance for years to come.
- Precision Fitment: Direct Bolt-On Installation: Designed for a perfect fit, this Kooks axle-back system is a direct bolt-on replacement for your factory exhaust, ensuring a hassle-free installation on all 2006-2013 C6 Z06 and 2009-2013 C6 ZR1 Corvettes. The two-piece design makes it much easier to install and remove vs the one piece oem muffler assemblies.
