McLaren 720S – Valved Exhaust System

Double X-Pipe Architecture • Valve Flexibility

Overview

The McLaren 720S is one of the fastest production cars in the world, capable of sub-10-second quarter miles right off the showroom floor. But the 4.0L twin-turbo V8 doesn’t quite deliver the exotic sound experience to match its performance. The Valvetronic Designs Valved Exhaust System fixes that. This full 3.0" titanium system is engineered to sharpen throttle response, reduce weight, and unleash a refined yet aggressive motorsport soundtrack.

F1 System

The Valvetronic Designs F1 system uses our bespoke double x-pipe configuration to bring an exotic, high pitch tone to the 720s. These vehicles tend to sound flat with a single x-pipe, but our proprietary double x-pipe makes the 4.0L twin turbo V8 have similar sound characteristics to that of a flat plane crank Ferrari.

Valved System

Our design incorporates a valved X-pipe with an integrated muffler to bring balance and tone. The system offers a civil, comfortable driving experience with valves closed, and with valves open, it delivers an intoxicating, F1-inspired wail that truly matches the 720S’ supercar status. Controlled via a stand-alone vacuum valve system and key fob, the power to choose your soundtrack is always at your fingertips.

Sound & Driving Experience

Valves Closed: Subtle and composed, perfect for street driving or long highway cruises.

Valves Open: Crisp, high-pitched motorsport tone with a sharper edge—refined volume but unmistakably exotic.

With Free-Flow Downpipes (optional): Significant sound increase, faster spool, and paired with a proper tune, the system produces aggressive pops, crackles, and flames.
