Akrapovic Evolution Header Set (Titanium) Porsche 991 RS

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 Akrapovič’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
