Akrapovic Evolution header set (Titanium). Porsche 991.2 GT3 RS / Speedster 2019>> with OPF/GPF filter
Code: E-PO/T/6/1
Akrapovic Evolution header set (Titanium)

akrapovic

Fits:
Porsche 911 GT3 RS (991.2) with OPF/GPF 2019 - 2020
Porsche 911 Speedster with OPF/GPF 2019 - 2020

Evolution Header Set (Titanium) must be mounted together with:
• Slip-On Line (Titanium) system S-PO/TI/15
or
• Slip-On Race Line (Titanium) system S-PO/TI/8.
An additional original Porsche stock bracket (Porsche p/n: 99111147391) is required for mounting the Akrapovič exhaust system. Please read the instructions carefully before the start of the installation.



Evolution Header Set converts the slip-on system into a full system designed to give noticeably increased power at higher revs. Handcrafted titanium headers incorporate 100 cpsi sports catalytic convertors and side mufflers—all designed to increase power and torque—the Evolution Header Set utilizes integrated catalytic convertors and the functionality of the exhaust valves to deliver an out-and-out attack on the senses. With the valves in the open position, it delivers a sportier and hard-hitting sound, 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.

When installing Akrapovič 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 Akrapovič 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.
