Product Description

Unlock the full performance potential and motorsport-inspired sound of your Porsche 718 Cayman GT4 RS or Spyder RS with the Akrapovič Evolution Header Set (Titanium). Developed specifically for Porsche's high-revving 4.0L naturally aspirated flat-six engine, these premium titanium exhaust manifolds combine advanced exhaust flow engineering, substantial weight savings, and race-proven technology to deliver a more responsive and exhilarating driving experience.

Designed as the ultimate addition to Akrapovič's titanium exhaust system for the GT4 RS and Spyder RS, the Evolution Header Set was developed and tested alongside the Akrapovič Slip-On Race Line (Titanium). When combined with the corresponding titanium link pipes, the complete exhaust system delivers significant improvements in horsepower, torque, exhaust response, and sound.

At the heart of the Evolution Header Set is a unique manifold runner crossover design, incorporated into each side of the exhaust system. This specialized configuration is engineered to optimize exhaust gas movement and improve engine performance throughout the midrange, where additional torque can have a substantial impact on acceleration and throttle response.

Unlike conventional exhaust headers, which may prioritize peak power at the expense of midrange performance, Akrapovič's crossover design is developed to improve the overall power delivery of Porsche's naturally aspirated flat-six engine. The result is a more engaging driving experience, particularly when accelerating out of corners or transitioning through the engine's operating range.

The headers are manufactured from high-grade titanium, offering exceptional strength, corrosion resistance, and thermal durability while dramatically reducing weight compared with the original exhaust manifolds. Akrapovič reports a weight reduction of approximately 5.0 kg (10.9 lbs), representing roughly 51% less weight than the factory header assembly.

Reducing exhaust system weight is especially valuable in the Porsche 718 GT4 RS and Spyder RS, where lightweight construction and vehicle balance are central to the driving experience. The titanium headers eliminate unnecessary mass while maintaining the durability required for demanding high-temperature motorsport applications.

Akrapovič also incorporates precision-cast components manufactured in its own titanium foundry. Among these are the specially developed three-into-one collectors, engineered to provide smooth exhaust gas transitions from the individual cylinder runners into the remainder of the exhaust system.

These collectors are designed to minimize unnecessary flow restrictions and support efficient exhaust scavenging, allowing the naturally aspirated engine to breathe more effectively throughout its operating range.

When installed with the Akrapovič Slip-On Race Line (Titanium) and Link Pipe Set (Titanium), the complete system produces manufacturer-reported gains of 35.4 metric horsepower at 4,900 rpm and 50.9 Nm (37.5 lb-ft) of torque at 4,900 rpm compared with the original factory exhaust system.

These figures were recorded during Akrapovič's dynamometer testing using a Porsche 718 Cayman GT4 RS. They represent the performance improvement of the complete exhaust configuration rather than the titanium headers installed independently.

Beyond measurable performance improvements, the Evolution Header Set dramatically enhances the exhaust character of Porsche's 4.0L flat-six engine. Akrapovič engineers the system to produce a distinctive high-performance racing sound, with pronounced engine harmonics, aggressive acceleration tones, and a sharp acoustic character during gear changes.

The headers are compatible with both OPF-equipped and non-OPF vehicles, allowing the same titanium header design to support different regional GT4 RS and Spyder RS configurations when paired with the appropriate exhaust components.

Because the Evolution Header Set is intended for maximum-performance competition applications, ECU remapping is mandatory following installation. The system is designed for closed-course racing environments and does not meet emissions compliance requirements for public road or highway use.

For Porsche 718 GT4 RS and Spyder RS owners building a dedicated track-focused vehicle, the Akrapovič Evolution Header Set provides an exceptional combination of advanced titanium engineering, substantial weight reduction, increased exhaust performance, and unmistakable motorsport sound.
