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

These short HJS sport-catalyst assemblies discharge through the GT2 RS rear bumper in place of the original catalyst-and-muffler layout. Choose them for a non-valved exhaust arrangement, rather than a replacement that retains PSE control. 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.
