Akrapovič exhaust system, manufacturer part number E-PO/T/7, for PORSCHE 911 GT3 / GT3 TOURING (992) 2021-2024.

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 Akrapovič 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 Akrapovič 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 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.
