Description
The CARGRAPHIC X-Pipe Sport Rear Silencer (RACING) is the most extreme exhaust upgrade for the Porsche 718 Spyder RS 4.0L and Cayman GT4 RS 4.0L. Engineered from lightweight SS304L stainless steel with CNC mandrel-bent pipework, it delivers maximum flow, reduced backpressure, and an unmistakably aggressive sound profile.
This system features a true X-pipe design with merged exhaust flow, combined with dual 3" (76.20mm) vacuum-controlled valves (PLO – pressureless open). Two 50.80mm bypass pipes route gases into a compact oval silencer, while valves open to unleash the full RACING SOUND – a sharp, raw exhaust note that amplifies with revs.
Weighing 12.90kg (saving 3.20kg over OEM’s 16.10kg), it not only enhances acoustics but also improves throttle response, torque delivery, and overall drivability.
Note: SOUND PLUS / RACING SOUND Export Version – Motorsport use only, no homologation.
