Fabspeed High-Flow Catalytic Converters for Porsche 991.2 Carrera with PSE (2017–2019)

Description

The Fabspeed Sport Cats for Porsche 991.2 (2017–2019) equipped with Porsche Sport Exhaust (PSE) are high-flow performance catalytic converters engineered to reduce exhaust backpressure and enhance throttle response while preserving emissions function and avoiding catalyst-related check engine lights. Designed as a direct bolt-on replacement for the restrictive factory catalytic converters, these sport cats improve flow and sound character under acceleration—particularly when combined with performance headers or full exhaust upgrades. Precision-crafted from thick-wall T304L stainless steel with high-flow German-imported 200-cell HJS catalysts, this upgrade delivers a noticeable improvement in responsiveness and mid-range power delivery for twin-turbo flat-six Porsche engines.
