Fabspeed Valved X-Pipe Exhaust for McLaren GT / GTS

Replace the McLaren rear muffler with a valved X-pipe that retains the matching factory exhaust controls. Confirm that the vehicle originally has exhaust valves; the separate Supersport system is the alternative identified for a non-valved car. 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

For a GTS, confirm the exact original exhaust interface and supplied hardware before ordering. A GT application description alone does not establish GTS compatibility.
