Fabspeed Valvetronic X-Pipe Exhaust System for 982 Porsche 718 Cayman GT4 RS & 718 Spyder RS

Fabspeed Valvetronic X-Pipe Exhaust System for 982 Porsche 718 Cayman GT4 RS & 718 Spyder RS

Fabspeed’s proprietary X-pipe design transforms the GT4 RS’s exhaust note while adding significant power compared to the stock GT4 RS rear exhaust. The X-pipe gives the GT4 RS the same high-pitched wail as the GT3 and integrates seamlessly with the factory exhaust valve system, allowing the driver to quiet the exhaust using the factory PSE button. The design process began with 3D scanning the entire OEM exhaust system using the CREAFORM 700 Handscan, enabling the creation of a complete SolidWorks 3D model. From there, Fabspeed designed the exhaust and fixtures to ensure perfect fitment to OEM standards. After multiple revisions for sound and dyno testing, the decision was made to use Fabspeed’s signature investment cast X-pipe to connect the FLAT 6 engine’s right and left cylinder banks, improving exhaust scavenging and reducing resonance. The system also incorporates Helmholtz resonator technology to eliminate drone by canceling unwanted frequencies.

Sound

• Wondering why the GT4 RS doesn’t have the same high-pitched scream as the GT3? The Fabspeed valvetronic x-pipe is the solution! The x-pipe design merges the two exhaust banks, creating an intoxicating 9000rpm symphony. While this system provides a significant increase in volume over stock, the valved design allows for volume control via the factory PSE (Porsche sport exhaust) button, ensuring a drone-free driving experience when desired.

Power

• When comparing the development car equipped with Fabspeed’s over axle link pipes, the valved x-pipe added +7.5hp (+6.2whp) at 8100rpm and +11ft/lbs at 3500rpm. Fabspeed designed and dyno-tested multiple systems before selecting the optimal system for both sound and horsepower. With over 30 years of experience, Fabspeed is trusted to deliver top-tier performance upgrades.
