Fabspeed McLaren 720S Supersport Inconel X-Pipe

The Fabspeed McLaren 720S Supersport X-Pipe Inconel 625 Exhaust System is a high-performance cat-back exhaust developed for the McLaren 720S Coupe and Spider, combining an advanced aerospace-grade material with a high-flow X-Pipe configuration.

Designed for McLaren 720S vehicles from 2018 onward, the system is engineered as a direct replacement for the heavy and restrictive factory muffler system while retaining the vehicle's OEM catalytic converters.

The exhaust is hand-fabricated from Formula 1-grade Inconel Ni625 / Inconel 625L, an advanced nickel-based alloy selected for its exceptional strength, oxidation resistance and ability to withstand extreme exhaust temperatures. Fabspeed highlights its use in Formula 1, IndyCar, Le Mans and Daytona racing applications.

The X-Pipe configuration is developed using Fabspeed's in-house CAD engineering and is designed to maximize exhaust flow while smoothing the exhaust path. This helps transform the factory character of the 720S into a more pronounced exotic sports-car soundtrack.

Compared with conventional stainless-steel construction, the Inconel material provides an exceptional combination of high-temperature durability and lightweight performance. Fabspeed specifically positions the system as a premium alternative to titanium, with the ability to withstand demanding thermal conditions for extended periods.

The system uses V-band flange construction for precise alignment with factory components and is engineered as a direct bolt-on cat-back replacement. No cutting or welding is required for installation.

Because the system is cat-back and retains the factory catalytic converters, Fabspeed states that it does not alter the vehicle's emissions configuration or factory warranty requirements and is street legal for the specified application.

For McLaren 720S owners seeking an uncompromising exhaust upgrade, the Supersport X-Pipe Inconel 625 combines Formula 1-derived material technology, high-flow engineering, extreme heat resistance and a distinctive high-pitched V8 sound.
