High flow metallic cats by HJS Motorsport http://www.hjs-tuning.de/en/3/105/0/seite_1/Technics/Sport-Catalytic/sport_catalytic.html for Porsche 997 Turbo mk2 (997.2) and Porsche 991 Turbo mk1 & mk2.CAUTION: because the OEM catalytic converters are replaced it may cause the triggering of the Check Engine Light caused by an O2 sensor error.ECU tuning is recommended.Thanks to the reduced backpressure compared to the OEM unit this component allows for a quicker turbo spool up and a consistent power and torque increase in the whole rev range.
