The Akrapovič Evolution Header Set (Titanium) is a race-inspired upgrade engineered to elevate the performance and sound of the Porsche 911 GT3 RS and 911 S/T (992.1). Tested and developed alongside the Slip-On Race Line (Titanium), this header set optimises gas flow and enhances midrange power, making it the perfect addition for track-focused enthusiasts. Crafted entirely from high-grade titanium, it achieves significant weight savings and showcases innovative manifold crossover pipes cast in Akrapovič’s in-house titanium foundry. This groundbreaking design has been derived directly from Akrapovič motorsport applications.
Sound
The Evolution Header Set redefines the auditory experience of the Porsche 911 GT3 RS. Featuring tuned quarter-length resonators and catalytic converters, the system eliminates unwanted frequencies and distortion, delivering a unique, exhilarating sound. The result is a rich, high-frequency exhaust note with a +10.1 dB increase at 3,750 rpm, enhancing the car’s visceral driving experience while reflecting Akrapovič’s motorsport heritage.
Performance
Engineered for closed-course competition circuits, the Evolution Header Set unlocks the true potential of the Slip-On Race Line system. By further reducing back pressure and optimising exhaust routing, this upgrade delivers combined impressive gains of +19.6 hp at 4,4750 rpm and +36.4 ft-lb of torque at 2,600 rpm. The titanium construction reduces weight by 3.8 kg, making it 28% lighter than the stock headers. This weight reduction improves vehicle agility, handling, and overall balance. When paired with the Slip-On Race Line, this combination transforms the GT3 RS into even more of a track-ready powerhouse. ECU remapping is mandatory for vehicles equipped with particulate filters (OPF) and recommended for non-OPF vehicles to maximise performance and prevent warning signals.
Design
Every detail of the Evolution Header Set reflects Akrapovič’s engineering expertise and dedication to quality. The innovative manifold crossover pipes are meticulously cast in Akrapovič’s in-house titanium foundry, ensuring precise fitment and optimal gas flow. The sandblasted and coated titanium construction enhances durability and aesthetics, while the lightweight design contributes to the system’s overall performance gains. Designed and built for seamless integration, this is a hardware upgrade with no compromises.
When installing the Akrapovič Evolution Header Set (Titanium) on vehicles with particulate filters, remapping the ECU is mandatory to prevent potential “check engine light” warning signals. When installing the Akrapovič Evolution Header Set (Titanium) on vehicles without particulate filters, remapping the ECU is recommended.
This system fits also on vehicles equipped with Otto particulate filter (OPF).
