McLaren 720S F1 Performance Valved Exhaust System

McLaren 720S F1 Performance Valved Exhaust System

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 contact@yonristic.com 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.

True F1 X-Pipe Acoustic Design

The core of this system is the precision-engineered F1-style X-pipe architecture, designed to completely transform how exhaust pulses interact across both turbo banks. Unlike conventional layouts that simply merge flow, this design carefully manages pulse timing and crossover behavior to refine the harmonic structure of the exhaust note. The result is a significantly sharper, higher-frequency sound with a clean, exotic character that builds naturally with RPM. It eliminates the muted and compressed tone of the factory system, replacing it with a more dynamic, motorsport-inspired sound that feels alive under throttle and screams at high revs.

Remote-Controlled Valve System (Standard)

This system comes standard with a dedicated remote valve control module, giving you full command over the exhaust behavior at any time. With a single input, you can switch between a quiet, controlled mode for daily driving and a fully open configuration that delivers maximum volume and unrestricted flow. Unlike factory systems that often limit valve opening based on driving conditions, this setup allows true 100% valve opening whenever desired. The result is a system that adapts instantly to your needs—refined and comfortable when cruising, yet aggressive and track-ready when fully opened.

For vehicles equipped with the factory valve package, OEM valve integration is available upon request. If you wish to use factory valve control, please contact us directly before placing your order so we can configure the system accordingly.

Heat-Protected Downpipes

For those looking to push the platform further, the system is designed to integrate seamlessly with our optional high-performance downpipes. Available in both free-flow catless and 200-cell high-flow configurations, these downpipes significantly reduce restriction and unlock additional power and sound intensity. Each unit is wrapped in advanced gold heat-resistant shielding, helping to manage extreme temperatures within the engine bay and protect surrounding components under high-performance driving conditions. Together with the catback system, this creates a fully optimized exhaust setup that enhances both performance and long-term reliability.
