Akrapovic Performance Exhaust — S-PO/TI/24

The Akrapovič Slip-On Race Line (Titanium) is a precision-engineered exhaust system that brings out the true character and performance of the Porsche 718 Cayman GT4 RS and Spyder RS. Crafted entirely from lightweight, high-grade titanium with a sandblasted finish, 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 track-focused 718 variants deserve and how they should have come from the factory. With motorsport-inspired engineering, this system sets a new benchmark for track-focused upgrades.

Sound

The Akrapovič Slip-On Race Line (Titanium) amplifies the Porsche's iconic flat-six engine note, delivering a deep and harmonious tone at lower speeds, transitioning to a true racing quality with high-frequency tones at higher revs. Tailored by two in-house cast titanium valves, the system delivers a +7.0 dB increase, creating a richer and more dynamic exhaust note that dramatically enhances the driving experience without being overpowering. Designed to maintain refinement, it eliminates unpleasant droning or streaming noise, ensuring an engaging and balanced sound profile in all driving conditions.

Performance

The Slip-On Race Line delivers impressive performance gains while significantly reducing weight. Dyno testing against the stock system recorded a power increase of +7.6 hp at 4,950 rpm and a torque gain of +14.2 ft-lb at 2,250 rpm. The system’s lightweight titanium construction reduces weight by 7.6 kg—a 44% reduction over the stock exhaust—enhancing handling and agility on the track. Installation requires no ECU remapping, allowing seamless integration with the vehicle’s factory setup.

Further performance upgrades can be achieved with the optional, modular components: 

• Link Pipe Set (Titanium): Achieves a power gain of +26.5 hp at 4,950 rpm and a torque increase of +28.1 ft-lb at 4,900 rpm, reducing weight by an additional 4.9 kg (38.9%).

• Evolution Header Set (Titanium): Delivers a total performance increase of +35.4 hp and +37.5 ft-lb from stock, with a further weight reduction of 5.0 kg (51.4%).

Design

The Akrapovič Slip-On Race Line features a sophisticated construction that balances form and function. The tailpipes are larger than the stock system, with an outer shell that is coated for durability and an inner cast shell left uncoated. This uncoated interior reacts to heat, developing an attractive blue colouration over time—a signature feature of Akrapovič craftsmanship. Each tailpipe is laser-engraved with the Akrapovič logo, emphasizing the brand’s premium aesthetic. Optional rear carbon-fibre diffusers in matte or high gloss are available to complement the system’s track-ready design, offering both style and a sizeable weight reduction.

Modern emissions and noise regulations often stifle the sound and performance of track-oriented cars, but the Akrapovič Slip-On Race Line (Titanium) restores the visceral experience the Porsche 718 Cayman GT4 RS and Spyder RS deserve. Designed and built for seamless integration, this is a hardware upgrade with no compromises.
