Akrapovic Evolution Header Set (Titanium) Porsche 911 GT3 (991) 2014 2017

The Evolution Header Set converts the slip-on system into a full Evolution Line system designed for noticeably increased power at higher revs, with parts cast in Akrapovič's own titanium foundry and a coating finish.

• Newly developed exhaust manifold with 100 cpsi sports catalytic converters and side mufflers
• Integrated catalytic converters and new exhaust valves: with valves open it sounds like the Evolution Race system; with valves closed a lower sound level for everyday use
• Weight savings behind the engine and rear axle to enhance handling
• Sportier, hard-hitting sound that builds as the engine revs
• Optional handcrafted carbon-fibre rear diffuser available

When installing Akrapovič aftermarket optional link pipes with or without sports catalytic converters, developed for use on closed tracks only, remapping the ECU is mandatory. For any closed-track exhaust system, remapping is recommended to prevent potential “check engine light” warnings.
