Fabspeed Valved Sport Catalysts for Porsche 991.2 GT2 RS (2018+)

Keep the GT2 RS exhaust-valve function while replacing its original catalysts with larger HJS sport-catalyst assemblies. This upgrade sits ahead of the rear muffler; it is not a complete exhaust system. Fabspeed Motorsport, based in Fort Washington, Pennsylvania, develops exhaust systems, air intakes and ECU tuning for sports cars including Porsche. Its development work uses dynamometer testing, road evaluation and racetrack testing.
