Sport Catalytic Converter
Fabspeed's HJS Sport Catalytic Converter for the 718 Boxster and Cayman (Base/S Worldwide 2017+, GTS 2017-2020) swaps the restrictive factory 750-cell ceramic catalyst for a German-made 200-cell German manufacturer of the high-flow catalytic converters Fabspeed fits in its sport cat products. HD unit, EURO 6 certified. On Fabspeed's dyno it added 8.5hp and 18 ft-lbs of torque at peak, with 13whp and 17 ft-lbs at 4000rpm, without triggering a check engine light and with no tune required. It installs with a Torca clamp into the factory double-walled exhaust, a simple cut that's fully reversible back to the stock catalytic converter on the same clamp.
