Product Overview

Crafted in Slovenia, the Akrapovič Evolution Header Set (Titanium) is a performance upgrade designed for the 2025 Porsche 911 GT3 and GT3 Touring (992.2). Made from high-grade titanium, this header set reduces weight, enhances engine output, and refines the exhaust sound. Developed to complement the Slip-On Race Line (Titanium) exhaust, it’s built for seamless integration, making it an excellent choice for drivers looking to improve their vehicle’s track performance and driving experience.

Performance Specifications

Designed for closed-course competition, this header set optimizes exhaust flow and reduces back pressure to boost engine performance. When paired with the Slip-On Race Line exhaust, it delivers:

+31.6 horsepower at 4,450 rpm
+35.6 ft-lb of torque at 4,650 rpm
3.8 kg weight reduction (28% lighter than stock headers)

These gains enhance vehicle agility, handling, and responsiveness. ECU recalibration is required for vehicles with particulate filters (OPF) and advised for non-OPF models to ensure optimal performance and prevent warning indicators.

Sound Profile

The Evolution Header Set enhances the Porsche’s flat-six engine with a +10.1 dB sound increase at 3,750 rpm. Equipped with tuned quarter-length resonators and catalytic converters, it produces a clear, high-frequency exhaust note while eliminating unwanted noise. The result is a refined yet powerful sound that complements both spirited driving and track use, drawing on Akrapovič’s motorsport expertise.

Design and Construction

The header set features precision-cast manifold crossover pipes, produced in Akrapovič’s in-house titanium foundry, ensuring accurate fitment and efficient gas flow. The sandblasted, coated titanium construction balances durability with a sleek appearance, while the lightweight design contributes to improved vehicle dynamics. Every component is engineered for reliability and a precise fit under the Porsche 911’s chassis.

Compatibility and Compliance

Compatible with the 2025 Porsche 911 GT3 and GT3 Touring (992.2), this header set is designed for track use but integrates smoothly with the vehicle’s existing systems. ECU recalibration is mandatory for OPF-equipped vehicles and recommended for others to maintain performance and avoid warning lights.

Warranty

Supported by a 2-year Akrapovič warranty.

Installation Notes

For vehicles with particulate filters (OPF), ECU recalibration is required. It is also recommended for non-OPF vehicles to ensure proper operation.
