The Fabspeed McLaren 720S Supersport LT Style Exhaust System is a high-flow cat-back exhaust developed for the McLaren 720S, replacing the heavy and restrictive factory muffler system with a performance-focused LT-style configuration.
Designed for McLaren 720S Coupe and Spider models from 2018 onward worldwide, the system is engineered as a direct replacement for the factory rear exhaust components while maintaining the factory catalytic converters.
Fabspeed lists performance figures of up to +55 hp and +54 TQ, with approximately -9 lb of weight compared with the factory configuration. These figures are based on testing under specific vehicle and ambient conditions, so actual results can vary between vehicles.
The Supersport LT Style system uses 3-inch (76 mm) T304L stainless steel tubing, fabricated with high-quality TIG welding. Fabspeed developed the system using direct SolidWorks flow analysis to optimize exhaust flow characteristics and improve overall performance.
Its LT-style configuration is designed to produce a distinctive 675 LT-inspired sports-car sound, giving the 720S a more aggressive and exotic exhaust character. The smoother exhaust flow also contributes to a more pronounced high-performance driving experience.
The system uses V-band flange construction for precise fitment with the factory components and is engineered as a direct replacement cat-back system. Installation is bolt-on, requiring no cutting or welding.
Because the system is cat-back and does not replace the factory catalytic converters, Fabspeed states that it does not alter the vehicle's emissions configuration or factory warranty requirements.
For McLaren 720S owners seeking a more aggressive exhaust character and increased performance, the Supersport LT Style Exhaust combines high-flow engineering, lightweight stainless-steel construction and a distinctive 675 LT-inspired sound.
