Supersport X-Pipe Exhaust System

The Fabspeed Motorsport McLaren GT Performance Package is engineered to provide a comprehensive solution for maximizing the performance, handling, and driving excitement of your 2020+ McLaren GT. Building on extensive experience with the 720S, this package integrates their Supersport X-Pipe Exhaust, high-flow Sport Cats featuring HJS German imported catalytic converters, BMC F1 Replacement Air Filters, and a custom-developed XperTune ECU Tune. The package is constructed from durable CNC mandrel-bent T304L stainless steel, ensuring longevity and optimal exhaust flow. Designed using 3D scans of OEM headers, it achieves a perfect bolt-on fitment, simplifying installation with no cutting or welding required. This complete hardware and software solution is built and tested in-house at Fabspeed Motorsport USA for reliable and exhilarating power gains. The HJS catalytic converters are highlighted for their high-grade materials, performance, and ability to provide a "straight pipe sound" while still meeting emissions standards. Significant performance increases are confirmed by dyno testing, showing gains of 118 whp and 168 ft-lbs of torque, along with a weight saving of 15 lbs compared to the factory components. The XperTune ECU Tune was specifically developed by Fabspeed to complement their high-flow exhaust system, unlocking the full potential of the hardware. It's important to note that this upgrade requires sending your ECU to Fabspeed for re-programming. Detailed instructions will be provided via email after checkout, and an ECU Information form must be included when sending your ECU. Fabspeed also offers the service to save your stock ECU settings, allowing you to revert to stock for a fee.
