Fabspeed Titanium Valvetronic X-Pipe Cat-Back Exhaust System for 982 Porsche 718 Cayman GT4 RS

Unleash the 982 Porsche 718 Cayman GT4 RS and Spyder RS with Fabspeed’s Titanium Valvetronic X-Pipe Cat-Back Exhaust System, engineered to deliver a higher-pitched wail, significant power gains, and true plug-and-play control via the factory PSE valve button. Developed entirely in house, the system was 3D scanned with a Creaform 700 HandScan, modeled in SolidWorks, and refined through multiple sound revisions and real dyno testing. Fabspeed’s investment-cast X-pipe links the flat-6’s left and right banks for superior scavenging and reduced resonance, while integrated Helmholtz resonators target and cancel drone for a clean, race-bred soundtrack on demand. Lightweight titanium construction, OEM-quality fit, and proven reliability make this the best-sounding, most powerful valved rear section available for the GT4 RS.

Sound

• For drivers seeking the GT3’s high-pitched character from a GT4 RS, Fabspeed’s Valved X-Pipe provides the answer. The X-pipe merges the flat-6’s two banks for an intoxicating 9000rpm soundtrack, while the valved design retains factory PSE control to moderate volume and maintain a drone-free cabin when desired. Built from long-run, mandrel-bent titanium tubing, the system minimizes welds and turbulence for superior flow, durability, and finish compared to multi-piece pie-cut constructions.

Power

• On Fabspeed’s development car already fitted with Over Axle Link Pipes, the Valved X-Pipe added +7.5hp (+6.2 whp) at 8,100rpm and +11ft-lbs of torque at 3,500rpm. Fabspeed designed and dyno-tested multiple configurations before selecting the optimal system for sound and performance, backed by over 30 years of experience.
