Fabspeed Valved X-Pipe Catback Exhaust System stainless steel for Porsche 718 GT4RS/Spyder RS

Engineered for drivers seeking the ultimate balance of performance, sound control, and lightweight construction, the Fabspeed Valved X-Pipe Catback Exhaust System in stainless steel transforms the driving experience of the Porsche 718 Cayman GT4 RS and Porsche 718 Spyder RS. Designed and manufactured from premium T304L stainless steel, this high-performance exhaust system delivers increased exhaust flow, reduced backpressure, and a significantly more aggressive motorsport-inspired exhaust note while maintaining daily drivability.

At the heart of the system is Fabspeed’s signature X-pipe design, engineered to optimize exhaust scavenging and improve power delivery across the RPM range. The result is sharper throttle response, enhanced flat-six character, and a smoother, higher-pitched exhaust tone reminiscent of Porsche’s factory race cars. Integrated valve functionality allows drivers to switch between a more refined street mode and an unrestricted race-inspired sound profile at the push of a button, offering versatility for both daily driving and track use.

The precision-built stainless steel construction provides exceptional durability, heat resistance, and corrosion protection while reducing overall system weight compared to the factory exhaust. Designed as a direct bolt-on catback solution, the system utilizes factory mounting locations for seamless installation and OEM-quality fitment. Compatible with factory catalytic converters and many aftermarket performance components, the Valved X-Pipe Catback is an ideal upgrade for enthusiasts looking to maximize both sound and performance from their GT4 RS or Spyder RS
