AKRAPOVIC Evolution Header Set (Titanium) (2021-2022 Porsche 911 GT3)

This 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 perfectly direct the gas flow. Showcasing the special manifold crossover pipes in the headers, cast in the Akrapovic in-house titanium foundry, this innovative design comes directly from race-proven exhaust systems, and this is the first time it has featured in an Akrapovic aftermarket car exhaust. This masterpiece of engineering is designed solely to optimize the performance of the Slip-On Race Line (Titanium) in the midrange. 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 Akrapovic 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 Akrapovic dyno against a Porsche 911 GT3 (992) with a standard stock exhaust. When installing the Akrapovic 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 Akrapovic Evolution Header Set (Titanium) on vehicles without particulate filters, remapping the ECU is recommended.
