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.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eSound\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe Evolution Header Set redefines the auditory experience of the Porsche 911 GT3. Featuring tuned quarter-length resonators and catalytic converters, the system eliminates unwanted frequencies and distortion, delivering a unique, exhilarating sound.

By further reducing back pressure and optimising exhaust routing, this upgrade delivers combined impressive gains of \u003cstrong\u003e+22.6 hp at 4,550 rpm\u003c\/strong\u003e and \u003cstrong\u003e+26.0 ft-lb of torque at 4,500 rpm\u003c\/strong\u003e. The titanium construction reduces weight by \u003cstrong\u003e3.8 kg, making it 28% lighter\u003c\/strong\u003e 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 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.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eDesign\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eEvery detail of the Evolution Header Set reflects Akrapovič’s engineering expertise and dedication to quality.
