Take your Porsche 718 Cayman GT4 RS to the next level with the Akrapovič Evolution Header Set, a motorsport-inspired performance upgrade engineered to maximize exhaust flow, reduce weight, and unleash the full potential of Porsche's naturally aspirated flat-six engine. Developed using technologies derived directly from professional motorsport, these titanium headers are designed for enthusiasts who demand uncompromising performance both on the road and on the circuit.
Manufactured entirely from premium-grade titanium, the Evolution Header Set combines lightweight construction with exceptional thermal resistance and structural strength. Akrapovič engineers have incorporated advanced manifold runner crossover sections and smooth-flow three-in-one collectors, all produced using precision in-house casting techniques. This sophisticated design optimizes exhaust gas scavenging, improves cylinder evacuation, and allows the engine to breathe more efficiently throughout the rev range.
Compared to the factory exhaust manifolds, the titanium construction achieves an impressive 5 kg (51.9%) weight reduction, improving overall vehicle dynamics while reducing mass behind the rear axle. The lower weight contributes to sharper handling characteristics and complements the naturally agile chassis of the Porsche 718 Cayman GT4 RS.
When paired with the Akrapovič Slip-On Line (Titanium) and Evolution Link Pipe Set (Titanium), the header system delivers remarkable performance improvements. Dyno testing performed by Akrapovič recorded gains of 26 kW (35.4 hp) and 50.9 Nm of torque at 4,900 rpm, providing noticeably stronger mid-range acceleration, faster throttle response, and an even more exhilarating driving experience.
Beyond measurable performance gains, the Evolution Headers transform the acoustic character of the GT4 RS. The carefully engineered runner design creates a sharper, more aggressive exhaust note with a distinctive motorsport-inspired tone that becomes increasingly exhilarating as engine speed rises. Gear changes become even more dramatic, delivering the authentic racing soundtrack expected from one of Porsche's finest naturally aspirated engines.
Designed exclusively for closed-course competition use, the Evolution Header Set requires ECU recalibration after installation to ensure proper engine management and optimal performance. The precision-engineered fitment allows seamless integration with compatible Akrapovič exhaust components while maintaining the exceptional manufacturing standards for which the Slovenian manufacturer is globally recognized.
Whether you're building the ultimate track-focused Porsche or pursuing maximum naturally aspirated performance, the Akrapovič Evolution Headers provide an outstanding combination of lightweight engineering, race-proven technology, and premium craftsmanship.
