Akrapovic Evolution Race Header Set (Titanium) - Porsche 911 GT3 RS (991.2) 2018 - 2020
The Akrapovič Evolution Race Header Set (Titanium) E-PO/T/5 for the Porsche 911 GT3 RS (991.2) is one of the most sought-after naturally aspirated Porsche exhaust upgrades available today.
Key Engineering Features
- Handcrafted Titanium Construction
- Much lighter than OEM stainless-steel manifolds.
- Reduces rear axle weight, improving turn-in response and agility.
- 100 CPSI Sports Catalytic Converters
- Considerably less restrictive than factory catalysts.
- Improves exhaust gas evacuation at high rpm.
- Titanium Flanges
- Cast in Akrapovič’s own foundry.
- Greater thermal stability and corrosion resistance.
- Designed for High-RPM Performance
- Power gains are concentrated from roughly 3,000 rpm all the way to the 9,000-rpm redline.
- Particularly suitable for the GT3 RS’s 4.0L naturally aspirated flat-six.
Why Enthusiasts Love It
For the 991.2 GT3 RS, the factory engine already produces around 520 hp. The real attraction of the Akrapovič header system is not merely horsepower:
- Sharper throttle response.
- Faster engine breathing at high rpm.
- Reduced back pressure.
- More aggressive motorsport sound.
- Noticeably improved downshift and overrun character.
Many GT3 RS owners report that header upgrades contribute more to the “Cup-car” experience than rear muffler changes alone because they fundamentally alter the engine’s breathing characteristics.
