This CES3 Version of the CAPRISTO Valved Exhaust System fits the Porsche 992 Carrera/S and 992 Turbo/S. It delivers dyno-proven gains of 4.9 PS (4.83 hp) and 18.7 Nm (13.79 lb/ft) while offering dual sound modes (subdued city driving / aggressive acceleration). This version replaces OE electric actuators with block-off adapters, utilizing vacuum actuators for standalone valve control independent of the factory system, enabling valves to remain open at idle and open earlier in the RPM range.
