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:

1. Sharper throttle response.
2. Faster engine breathing at high rpm.
3. Reduced back pressure.
4. More aggressive motorsport sound.
5. 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.
