Akrapovič Porsche 911 (991/991.2) GT3/GT3 Touring/GT3 RS Evolution Header Set
The Evolution Header Set transforms the slip-on system into a full Evolution Line system, designed to noticeably increase power at higher revs. With meticulous attention to detail, including components cast in Akrapovič’s own titanium foundry, the craftsmanship and coating finish of this system are truly impressive. The newly developed exhaust manifold, which incorporates 100 cpsi sports catalytic converters and side mufflers, is specifically designed to boost power and torque. The Evolution Line makes use of integrated catalytic converters and new exhaust valve functionality to deliver a truly exhilarating experience. When the valves are open, the Evolution Line produces a sound comparable to the top-performing Evolution Race system, but also offers the flexibility of a quieter sound level when the valves are closed, making it ideal for more everyday driving conditions. The system’s significant weight reduction behind the engine and rear axle enhances handling and improves overall performance. The Evolution Line is finely tuned to deliver a sportier, more aggressive sound—especially in open valve mode, where the sound intensifies as the engine revs higher—while also enhancing performance, offering an even greater sensory experience.
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 avoid potential “check engine light” warning signals.
THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR ROAD OR HIGHWAY USE.

For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
