Fabspeed Exhaust, Filter and ECU Package for McLaren GT / GTS (2020+)

Combine the Supersport X-pipe, sport catalysts, BMC filters and a matched XperTune calibration in one McLaren GT performance package. The ECU must be removed and sent for bench programming; this package uses the Supersport exhaust rather than the separate valved X-pipe. Fabspeed Motorsport designs performance exhaust systems, air intakes and ECU tuning in Fort Washington, Pennsylvania. Porsche and other sports-car applications are developed through dyno testing, road evaluation and racetrack work.

Before you order

Confirm exact McLaren GTS hardware and ECU compatibility before ordering a GTS application. Package contents and tuning must match the selected car.

Use restrictions

A sport catalyst, a STREET option label or the absence of a fault light does not establish public-road emissions approval. Confirm the requirements for the intended installation before ordering.
