Fabspeed Non-Valved Titanium Exhaust for Porsche GT4 RS / Spyder RS

Choose the lightweight fixed-volume titanium cat-back for the 718 RS models. Its cast titanium X-pipe replaces the rear exhaust arrangement without the selectable quiet-valve mode of the separate valved system. Based in Fort Washington, Pennsylvania, Fabspeed Motorsport designs exhaust, intake and ECU-tuning products for Porsche and other sports cars. Development includes evaluation on a dynamometer, on the road and at the racetrack.
