Spec: Duo 3” | Factory Valve Integration or Remote Valve Option
Engineered for those who expect more than just performance, designed for drivers who demand a true AMG experience.

The Mercedes-AMG GLC 63 and 63S redefine what it means to drive an SUV, with a handcrafted 4.0L Biturbo V8, fierce styling, and the unmistakable pedigree of AMG performance. Yet even this powerhouse leaves something on the table when it comes to sound and emotion. That’s where Yonristic Performance steps in—to unleash the full potential waiting inside.

The YR Performance duo 3” cat-back exhaust system elevates your GLC's tone, power, and responsiveness to a level befitting the AMG badge. Every aspect of this system is meticulously engineered for the M177 V8 platform, offering a bolt-on, fully reversible installation with OEM-quality fitment. Whether you want a refined burble around town or an unleashed roar under throttle, this exhaust adapts to your drive and your mood.

At the heart of the system is a true dual 3” design that minimizes backpressure and maximizes exhaust flow, paired with your choice of factory valve integration or our independent remote-controlled valves. This gives you the flexibility to maintain stock valve operation, or upgrade to full manual control over your sound experience.

Every system is constructed from premium 304 stainless steel or our signature titanium for ultimate weight savings, performance, and durability. Hand TIG-welded with care, finished to perfection, and tuned for a signature deep AMG tone that remains smooth and aggressive across the RPM range.

✔️ True dual 3” mandrel-bent piping – maximum flow, enhanced power
