Product Description

The Akrapovic Evo Header Set – S-PO/TI/8-TP-E-L is a race-bred titanium header upgrade engineered specifically for the Porsche 911 GT3. This premium titanium header set dramatically enhances exhaust flow, reduces rear-end weight, and unlocks strong mid-range horsepower and torque gains when paired with a Slip-On Race Line exhaust. The lightweight construction and tuned design bring an aggressive, pure exhaust note that compliments the high-revving flat-six character. Installation is engineered to integrate cleanly with existing Akrapovic exhaust hardware, giving track-focused drivers a significant performance and sensory upgrade.
