Evolution Header Set converts the slip-on system into a full Evolution Line system designed to give noticeably increased power at higher revs. With superb attention to detail, including parts cast in Akrapovic’s own titanium foundry, the craftsmanship and coating finish on the system is a joy to behold. With a newly developed exhaust manifold, incorporating 100 cpsi sports catalytic convertors and side mufflers—all designed to increase power and torque—the Evolution Line utilizes integrated catalytic convertors and the functionality of the new exhaust valves to deliver an out-and-out attack on the senses. With the valves in the open position, the Evolution Line sounds like the top-performing Evolution Race system, but also has the option of a lower sound level when the valves are closed, perfect for use in more everyday locations. Offering an increased weight savings in the area behind the engine and the rear axle, the reduction will enhance the handling and improve performance. The Evolution Line is also tuned to deliver a sportier and hard-hitting sound—in open valve mode, the more the engine is revved the better the sound gets—as well as increasing performance, all to provide an even greater sensory experience. With the addition of the handcrafted high-quality optional carbon- fibre rear diffuser, the Evolution Line will show that the GT3 means business even when it’s standing still.

When installing Akrapovic aftermarket optional link pipes with sports catalytic converters or without catalytic converters, which are developed for use on closed tracks only, remapping the ECU is mandatory. When installing Akrapovic aftermarket exhaust system that was developed for use on closed tracks, we recommend remapping the ECU in order to prevent potential check engine light warning signals.
