Lightweight titanium Valvetronic X-pipe cat-back exhaust system by Fabspeed, engineered specifically for the Porsche 718 GT4 RS and Spyder RS

Description

The Fabspeed Titanium Valvetronic X‑Pipe Cat‑Back Exhaust completely transforms your 718 GT4 RS / Spyder RS’s rear exhaust — delivering a dramatic, high‑pitched flat‑six wail, sharper throttle response, and real power gains over stock. Because it’s built around Fabspeed’s cast X‑pipe design and retains the factory exhaust valve system (PSE), you get a convertible exhaust personality: civilized and quiet when comfort matters, or aggressive and visceral when you want to really drive. The titanium construction keeps the system light, durable, and track‑ready, while offering a distinctive exhaust tone that elevates the driving experience to GT‑class performance.
