YR Performance Tips

The Yonristic Catback Exhaust System for the Porsche 911 (991.1) brings a new level of sound and performance to an already iconic platform. Known for its precision and power, the 991.1, while impressive, often left drivers wanting more in terms of exhaust tone and driving engagement. Our custom-built catback exhaust with valve control is designed to transform the auditory and performance experience of the 991.1, unlocking the full potential of Porsche’s legendary flat-six engine.

Crafted from T304 stainless steel or Grade 5 titanium, the Yonristic system significantly reduces weight while maintaining durability. The exhaust is meticulously engineered with an equal-length design, ensuring optimized exhaust flow for improved throttle response and reduced backpressure, enhancing both power and efficiency.

What sets this system apart is the integrated valve control technology. With the touch of a button, drivers can adjust the exhaust tone—ranging from a refined, everyday sound to a thunderous roar that accentuates the engine’s natural characteristics. This adjustable sound control ensures flexibility, whether you're cruising in comfort mode or pushing the limits on the track.

The aesthetic is further enhanced by our double-layered tips, adding a visual statement to the already aggressive rear of the 911. Easy installation and a seamless fit make this a plug-and-play upgrade, requiring no modifications to the OEM rear section.

For those seeking an upgrade that matches Porsche’s high standards of engineering while adding a layer of personalization, the Yonristic Catback Exhaust System with valve control is the ideal solution. It not only amplifies the raw sound of the flat-six but also elevates the performance of the 991.1, giving drivers full control over both sound and power.
