Akrapovic Performance Exhaust — S-PO/TI/10H
The Akrapovič Slip-On Line (Titanium) is a precision-engineered exhaust system that brings out the true character and performance of the Porsche 911 GT3, GT3 Touring, and GT3 RS (991.2). Crafted entirely from lightweight 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 these high-performance vehicles deserve and how they should have come from the factory.
Sound
The Slip-On Line transforms the auditory experience of the Porsche 911, unlocking the full potential of its naturally aspirated flat-six engine. At lower revs, the system delivers a rich, sporty tone that grows into a race-inspired roar at higher speeds. The titanium muffler design features Akrapovič’s specialised internal construction, including double-round tailpipes and optional link pipes, to ensure a dynamic exhaust note without any intrusive droning, both on and off the track.
Performance
The Akrapovič Slip-On Line (Titanium) is designed to optimise the performance of the Porsche 911 GT3, GT3 Touring, and GT3 RS (991.2). By reducing backpressure and improving gas flow, the system allows the engine to operate more efficiently, resulting in improved throttle response and stronger acceleration. Akrapovič’s dyno testing confirms measurable gains of +6.3 hp at 4,200 rpm and +7.7 ft-lb of torque at 4,200 rpm. The titanium construction reduces weight by 1.4 kg (16.1%), significantly enhancing agility, cornering precision, and overall handling. These benefits are achieved without the need for ECU remapping, ensuring seamless installation and compatibility with the GT3’s factory setup.
Design
The Slip-On Line’s titanium construction is engineered to the highest standards, with components such as the double-round tailpipes hand-finished to ensure flawless fitment and style. The system integrates seamlessly with the Porsche’s factory diffuser, or can be paired with an optional carbon fibre rear diffuser available in matte or high-gloss finishes, further enhancing the vehicle’s aggressive aesthetics. Precision craftsmanship and attention to detail ensure the system delivers both form and function.
Modern emissions and noise regulations all too often stifle the sound and performance of today’s sports cars. Akrapovič’s Slip-On Line addresses this, restoring the visceral sound and responsiveness that define the 911 GT3 as a true driver’s car. Designed and built for seamless integration, this is a hardware upgrade with no compromises.
Compliance, Compatibility, and Warranty
The Akrapovič Slip-On Line (Titanium) is fully ECE type-approved, ensuring compliance with emissions and noise regulations for road use. No ECU remapping is required ensuring seamless integration with the vehicle’s existing systems.
Warranty: Backed by Akrapovič’s 2-year product warranty.

-
Akrapovič dB Reducer (Titanium) TP-PO991GT3/BOX – The Akrapovič dB reducer lowers sound levels by 2–3 dB without compromising the system’s signature character. Made from lightweight titanium, this additional muffler expands exhaust gases to reduce dynamic noise while maintaining the Akrapovič tone. Easily installed in place of the tailpipe set, it works with all Akrapovič systems, including optional carbon fibre diffusers, for seamless compatibility.
-
Rear Carbon Diffuser (Matte or High-Gloss) – Available in matte or high-gloss finishes, this diffuser complements Akrapovič’s exhaust systems with a striking visual enhancement.
