Akrapovic Performance Exhaust — S-PO/TI/23

The Akrapovič Slip-On Race Line (Titanium) is a precision-engineered exhaust system that brings out the true character and performance of the Porsche 911 GT3, GT3 Touring, GT3 RS and S/T 992.1. Crafted entirely from lightweight, high-grade titanium, this system is designed to enhance every aspect of the driving experience—from sound and performance to weight savings and aesthetics. More than just an exhaust, it’s the finishing touch the 992 deserves and how it should have come from the factory. With motorsport-inspired engineering and a focus on lightweight performance, this system sets a new benchmark for track-focused upgrades.

Sound

The Akrapovič Slip-On Race Line delivers a +4.1 dB increase, enhancing the natural tone of Porsche’s iconic flat-six engine. It produces a smooth, rich sound at cruising speeds and transitions to a sportier, more aggressive note at higher revs. The housing of the exhaust valves – tailored to optimise gas flow – and the collectors in the muffler are cast in Akrapovič’s in-house foundry for precision and durability. This system ensures a dynamic and engaging exhaust note while eliminating intrusive droning, making it ideal for driving in all conditions.

Performance

The Akrapovič system for the 992 is engineered to maximise performance on the track by improving exhaust flow and reducing back pressure, all while achieving significant weight savings. This freer-flowing titanium design sharpens throttle response and enhances acceleration for a more engaging driving experience. No ECU remap is required when stock headers are retained and the Adapter Set is installed. However, for those upgrading to a full Evolution Line system with the Akrapovič Header Set, remapping the ECU is recommended to avoid Check Engine warning signals and ensure optimal performance.

These options give owners the flexibility to choose the setup that best matches their performance needs, whether retaining the factory headers for simplicity or upgrading to a full titanium system for maximum gains.

Design

Meticulously designed to match the Porsche 911’s iconic styling, the Slip-On Race Line combines functionality and aesthetics. The twin titanium tailpipes feature a sandblasted and coated finish, with six imprints on the inner sleeve to mirror the engine’s six cylinders. Akrapovič’s attention to detail extends to the in-house cast valve housings and muffler collectors, ensuring exceptional durability and performance. The lightweight construction is engineered to fit seamlessly within the car’s underbody, delivering both form and function for the ultimate track experience.

Modern exhaust regulations often restrict the true character of performance cars, but Akrapovič’s Slip-On Race Line (Titanium) brings the Porsche 911 GT3 and GT3 RS to life. With its lightweight titanium construction, thrilling sound, and race-proven performance, this system is the ultimate upgrade for track enthusiasts. Designed and built for seamless integration, this is a hardware upgrade with no compromises.
