Experience the special combination of sound, design, and performance provided by the Porsche Cayman GT4/Spyder Akrapovic Slip on Race Line. This stunning exhaust system has been perfectly tuned by Akrapovic sound engineers for a rich, harmonic, high-frequency tone from the system in the upper rev range and a deep sound in the lower range. With no drone and an enjoyable sound that lingers even after throttle release, you'll experience power gains of +4.8 kW at 3,000 rpm and a torque increase of +15.8 Nm at 2,900 rpm.
