Yonristic Performance S4/S5 2009-2023 Racing Valved Exhaust System

The Yonristic Catback Exhaust System for the Audi S4 is designed to elevate the performance and auditory experience of this popular sports sedan. Known for its balance between daily drivability and spirited performance, the Audi S4's stock exhaust system often leaves enthusiasts wanting more in terms of sound and responsiveness. That’s where our custom-built catback exhaust with valve control comes into play, delivering a more aggressive tone while enhancing the overall performance.

Crafted from T304 stainless steel or Grade 5 titanium, the Yonristic system sheds excess weight while maintaining exceptional durability and resilience. The precision-engineered design enhances exhaust flow, reducing backpressure and improving throttle response, resulting in optimized engine performance. Audi's turbocharged V6 deserves an exhaust system that can do justice to its power, and the Yonristic catback does exactly that.

What sets our exhaust apart is the integrated valve control system, giving drivers the ability to adjust the exhaust tone on demand. With just a press of a button, you can switch between a refined, subdued sound for daily drives and an exhilarating roar that brings the Audi S4's performance to life during spirited driving.

In addition to the acoustic benefits, the exhaust system is visually enhanced by double-layered tips, adding a distinctive, polished touch to the rear of the S4. The system fits seamlessly, requiring no modifications to the OEM setup, making it an easy, yet impactful upgrade.

For S4 owners who want to experience the full potential of their vehicle while personalizing their driving experience, the Yonristic Catback Exhaust System with valve control is the perfect solution. It amplifies the V6’s natural sound and power, delivering a driving experience that’s as thrilling as it is sophisticated.
