● Just crank up the volume and listen to the Porsche 718 Cayman GT4 RS screaming on the dyno. This beauty is powered by Porsche's 4.0 liter naturally aspirated flat-six engine that revs up to 9000rpm! Video features not one but 2 GT4 RS's; grey one is fitted with a JCR race exhaust and black one is fitted with a full Akrapovic titanium exhaust system.
