Akrapovič Porsche 911 GT3/GT3 Touring (991.2) Slip-On Line Exhaust System
The Akrapovič Slip-On Line exhaust system for the Porsche 911 GT3 (991.2) is designed as an ideal entry-level upgrade in performance exhaust systems. It’s constructed from high-grade titanium, making the GT3 more powerful and lighter, and it delivers the signature Akrapovič sound, all while maintaining compliance with ECE specifications.
Key Features:
- High-Grade Titanium Construction:
The lightweight design results in improved handling and performance by reducing overall vehicle weight. - Distinct Akrapovič Sound:
Produces a deep, rich tone, enhancing the car’s character without exceeding noise limits for street use. - Performance Gains:
Increases both power and torque, improving the GT3’s overall driving dynamics.
Visual Enhancements:
- Optional Carbon-Fibre Rear Diffuser:
To complement the system, a beautifully handcrafted carbon-fibre rear diffuser is available in matte or high-gloss finishes. This diffuser enhances the visual appeal of the titanium exhaust system, making the Porsche GT3 look even more exclusive.
Compliance Notice:
- This Slip-On system is ECE type-approved in its basic form.
- However, if you upgrade the system with the Link Pipe Set or the Evolution Header Sets, the ECE type approval will no longer be valid.
This system is perfect for Porsche GT3 owners looking to upgrade their car’s performance and sound while maintaining a street-legal exhaust system. The option to further upgrade with headers and visual enhancements makes it a versatile solution that can grow with your performance needs.
