Description
The CARGRAPHIC Sport Rear Silencer CLUBSPORT / TOURING is the ultimate performance exhaust upgrade for the Porsche 718 Spyder RS 4.0L and Cayman GT4 RS 4.0L. Developed from lightweight SS304L stainless steel with precision CNC mandrel-bent pipework, it combines maximum performance with refined acoustics.
Featuring a unique triangular silencer design with an acoustic resonator, this system eliminates drone and resonance while delivering a dynamic, race-inspired exhaust note. Integrated vacuum-controlled 70mm exhaust valves (PLO – pressureless open) allow seamless transitions between SOUND (valves closed, refined touring tone) and SUPER SOUND PLUS (valves open, aggressive unsilenced flow).
Weight savings of 2.45kg over OEM further enhance performance, while compatibility with factory or optional CARGRAPHIC tailpipes ensures complete flexibility.
Note: SOUND / SUPER SOUND PLUS Export Version – Motorsport use only, no homologation.
