EV - EvolutionThis product is made using high-grade titanium, with the parts sandblasted and coated for durability. This new header set has a routing that has been designed to perf ectly direct the gas flow.

Many parts in the headers are cast in the in-house foundry, and the complete use of titanium results in a weight saving of 3.8 kg, which is 28% lighter than the stock equivalent. Tuned quarter-length resonators in addition to the catalytic converters ensure the sound quality and the absence of any distortion or unwanted frequencies, creating a unique sound experience.The combination of an Akrapovič Slip-On Race Line (Titanium) and Evolution Header Set (Titanium), developed for use on closed-course competition circuits only, provides increases of 16.6 kW (22.6 hp) in power at 4,550 rpm and 35.2 Nm in torque at 4,500 rpm, when tested on the Akrapovič dyno against a Porsche 911 GT3 (992) with a standard stock exhaust.When installing the Akrapovič Evolution Header Set (Titanium) on vehicles with particulate filters, remapping the ECU is mandatory to prevent potential “check engine light” warning signals.When installing the Akrapovič Evolution Header Set (Titanium) on vehicles without particulate filters, remapping the ECU is recommended.This system fits also on vehicles equipped with Otto particulate filter (OPF).This product does not fit on RS version.
