Fabspeed Titanium Valved Exhaust for Porsche 718 GT4 RS / Spyder RS

Give the GT4 RS or Spyder RS a titanium X-pipe rear exhaust with selectable volume through the compatible original PSE controls. Helmholtz resonators are incorporated to manage unwanted cabin frequencies. Fabspeed Motorsport, based in Fort Washington, Pennsylvania, develops exhaust systems, air intakes and ECU tuning for sports cars including Porsche. Its development work uses dynamometer testing, road evaluation and racetrack testing.
