Description
Transform your McLaren GT or GTS into a more powerful and engaging grand touring machine with the Fabspeed Performance Package. Developed as a complete high-performance exhaust and ECU tuning solution, this package combines carefully engineered hardware and software upgrades designed to maximize power output, improve throttle response, and deliver an enhanced exotic exhaust experience.
Drawing from extensive development experience on McLaren’s high-performance platforms, Fabspeed engineered this package to optimize the performance characteristics of the twin-turbocharged V8 engine while maintaining reliability and everyday drivability. By integrating high-flow exhaust components, upgraded intake filtration, and custom ECU calibration, this package significantly improves airflow efficiency and engine performance throughout the RPM range.
The package includes a Fabspeed Supersport X-Pipe Exhaust, Fabspeed Sport Catalytic Converters, BMC F1 replacement air filters, and Fabspeed XperTune ECU software. Working together, these components create a complete performance solution that delivers substantial gains in horsepower and torque while reducing weight compared to the restrictive factory system.
The Supersport X-Pipe improves exhaust scavenging and reduces restriction, while the high-flow sport catalytic converters and BMC performance air filters enhance engine breathing efficiency. Fabspeed's proprietary XperTune ECU software optimizes engine parameters to fully maximize the benefits of the upgraded hardware.
The result is a more responsive and exhilarating driving experience with improved power delivery, sharper throttle response, and a more aggressive performance-inspired exhaust tone.
