Porsche 911 GT3 RS & Speedster 991.2 Evolution Header Set - OPF/GPF by Akrapovic

The Akrapovič Evolution Header Set (Titanium) converts the Slip-On Line into a full exhaust system for OPF/GPF-equipped Porsche 911 GT3 RS & Speedster (991.2).

Important — Mandatory Combination

This Evolution Header Set must be mounted together with the 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 also required for mounting. Please read the installation instructions carefully, and contact us before ordering to confirm your full parts list.

Handcrafted Titanium Headers, Integrated Catalytic Converters

Handcrafted titanium headers incorporate 100 cpsi sport catalytic converters and side mufflers, using the functionality of the exhaust valves to deliver an out-and-out attack on the senses. With the valves open, expect a sportier, hard-hitting sound; closed, a lower sound level suited to everyday use. Weight savings are concentrated behind the engine and over the rear axle, enhancing handling and performance.
