McLaren 720S F1 Performance Valved Exhaust System

F1 X-Pipe Architecture | Catback + Downpipe Options

Engineered for Pure F1 Sound. Built for the McLaren 720.

The McLaren 720S is one of the most capable supercars ever built, but its factory exhaust system softens the true character of its twin-turbo V8. The Yonristic Performance Exhaust System is designed to completely transform that experience through a true F1-inspired X-pipe architecture, delivering a sharper, higher-pitched, and far more exotic sound signature.

With a one-piece bolt-on design and remote-controlled valve system, this setup gives you full control over the sound—quiet and refined when needed, and fully unleashed when you want the true F1 experience.

Discover the Ultimate 720S F1 Performance Exhaust for Your McLaren 720S

The Yonristic Performance Exhaust System for the McLaren 720S is engineered to unlock the full acoustic and performance potential of the M840T platform.

At the heart of the system is a true F1 X-pipe design, developed to reshape how exhaust pulses interact across both turbo banks. By merging the flow through a precisely engineered crossover, the system enhances pulse timing and harmonic structure, producing a significantly higher-pitched, cleaner, and more exotic tone compared to the factory setup. The result is a sound that evolves with RPM—tight and refined at lower speeds, and aggressively sharp and screaming at high revs.

The exhaust is built as a one-piece direct bolt-on system, eliminating unnecessary joints and restrictions found in multi-piece designs. This not only improves overall flow efficiency but also ensures structural rigidity and long-term reliability. The simplified architecture allows for smoother exhaust gas transition, contributing to better throttle response and a more immediate driving feel.

The system comes standard with a remote valve control setup, allowing drivers to fully open or close the valves on demand. When closed, the exhaust maintains a more controlled and comfortable tone for daily driving. When opened, the system delivers a fully unrestricted exhaust path, producing maximum volume, sharper response, and the full F1-inspired sound character.

For vehicles equipped with the factory valve package, we also offer OEM valve integration upon request. If you would like to retain factory valve control through the vehicle’s drive modes, please contact us directly at [email protected] before placing your order so we can configure the system accordingly.

For those seeking even greater performance and sound, we offer optional downpipes designed to pair perfectly with the catback system:

• Free-flow catless downpipes for maximum performance and raw sound

• 200-cell high-flow catalytic downpipes for improved flow with reduced emissions impact

Both options are wrapped in gold heat-resistant shielding, reducing engine bay temperatures and protecting surrounding components under extreme conditions.

To complete the system, a range of premium exhaust tip options is available, including chrome, forged carbon fiber, matte black, burnt titanium, and gold finishes, allowing you to match the visual identity of your build.

The result is a complete exhaust solution that delivers perfect fitment, maximum performance, and a true F1-inspired sound—exactly what the McLaren 720S platform deserves.

Precision Engineering for Maximum Performance

The 720S F1 performance exhaust is expertly engineered to optimize the McLaren 720S's power output while enhancing exhaust flow efficiency. This advanced valved exhaust system balances sound and performance by allowing drivers to adjust the exhaust note based on their preference. Precision materials and craftsmanship ensure durability, reduced weight, and increased horsepower. Whether on the street or track, this system delivers a significant boost to throttle response and engine breathing, elevating the driving experience to new heights with unparalleled performance benefits.

Customizable Sound with Innovative Valve Technology

One of the standout features of the 720S F1 performance exhaust is its sophisticated valve control system. Drivers can seamlessly switch between a refined, quiet mode for everyday driving and a distinct, aggressive exhaust roar for spirited runs. This versatility allows personalization of the car’s acoustic presence, ensuring it suits any driving environment. The valved mechanism reduces drone on longer drives and enhances the iconic McLaren exhaust note when open, providing an exhilarating auditory experience while maintaining compliance with noise regulations.

Lightweight Design with Superior Materials

Constructed from premium-grade stainless steel and titanium components, the 720S F1 performance exhaust system significantly reduces the overall weight compared to the stock exhaust. This weight reduction contributes directly to improved handling and acceleration in the McLaren 720S. The corrosion-resistant materials guarantee long-term durability and maintain the system’s aesthetic appeal under harsh driving conditions. Additionally, the exhaust’s design complements the McLaren’s sleek lines, making it not only a performance upgrade but also a visual enhancement.
