Fabspeed Catalytic-Converter Re-Coring Service for Porsche Cayenne 957

Keep the accepted original 957 Cayenne catalyst housing while its internal core is replaced through Fabspeed’s HJS service. Identify the engine and market exhaust configuration first, then agree which housing and how many units are covered before shipment. Based in Fort Washington, Pennsylvania, Fabspeed Motorsport designs exhaust, intake and ECU-tuning products for Porsche and other sports cars. Development includes evaluation on a dynamometer, on the road and at the racetrack.
