Akrapovič Porsche 911 (991/991.2) GT3/GT3 Touring/GT3 RS Evolution Race Header Set
The Evolution Race Header Set transforms the slip-on system into a full system, specifically designed for the track, giving the Porsche GT3 the enhanced performance it deserves. Handcrafted titanium headers feature 100 cpsi sports catalytic converters and titanium flanges—cast in Akrapovič’s own foundry. This system delivers a perfectly smooth power curve from 3,000 rpm right through to the top of the power band, continuously increasing performance as the revs climb. Alongside improved torque and significant weight savings that enhance handling, the addition of the Evolution Race Header Set will make your car perform like a true cup racer—complete with a deep, loud, and powerful Akrapovič racing sound to match its performance.
When installing Akrapovič aftermarket optional link pipes with sports catalytic converters or without catalytic converters, which are intended for closed-track use only, remapping the ECU is mandatory. For any Akrapovič aftermarket exhaust system developed for closed-track use, we recommend remapping the ECU to prevent potential “check engine light” warning signals.
THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR ROAD OR HIGHWAY USE.
