The Porsche 718 Cayman GT4 RS is already one of the sharpest drivers’ cars on the planet, yet Akrapovic has developed a complete titanium exhaust system that takes this track weapon to new levels. Constructed from premium materials and shaped by extensive motorsport research, the Akrapovic Slip-On Race Line, Titanium Link Pipe Set, and optional Sound Kit transform the 718 GT4 RS into a lighter, more powerful, and sonically thrilling machine. Each component carries the brand’s signature attention to detail, offering proven gains in power, torque, and weight reduction while producing an exhaust note that reflects the car’s racing DNA.
The foundation of the system is the Akrapovic Titanium Slip-On Exhaust System. Built from high-grade titanium with a sandblasted finish, it features dual valves that deliver a refined tone at low rpm and an aggressive howl at higher revs. The enlarged tailpipes, with their heat-reactive blue hue, signal that this is no ordinary exhaust.
On Akrapovic’s dyno, the Slip-On Exhaust System delivered a 7.6 horsepower increase at 4,950 rpm and a torque bump of 19.3 Nm at 2,250 rpm compared to the stock system. Just as impressive is the 7.6 kg weight savings, shedding 44.4 percent over factory hardware. Designed for closed-course competition, the Slip-On Exhaust System requires no remapping on its own, making it a direct path to improved performance and sound.
Beyond the numbers, this exhaust system brings an entirely different level of engagement to the Cayman GT4 RS. Throttle response sharpens, and the naturally aspirated flat-six feels more alive as the revs climb. The titanium construction also enhances durability and heat resistance, ensuring consistent performance even under repeated track sessions. It is a true performance piece that blends form and function seamlessly.
For enthusiasts seeking the ultimate upgrade, the Titanium Link Pipe Set completes the system. Constructed from titanium with stainless steel housings, it incorporates 200 cpsi sport catalytic converters, heat shielding, and provisions for EGT sensor deletion when applicable. This section improves exhaust flow and further reduces weight, cutting an additional 4.9 kg compared to stock.
Paired with the Slip-On Exhaust System, the gains are substantial. Testing on the Porsche 718 Cayman GT4 RS showed an increase of 26.5 horsepower at 4,950 rpm and torque improvements of 38.1 Nm at 4,900 rpm. The system also delivers an unmistakable high-pitched race car sound, the kind of note that defines track-focused Porsche builds. Unlike the Slip-On, the Link Pipe requires ECU remapping to run correctly, ensuring that the car’s fueling and tuning are optimized for the freer-flowing exhaust.
The design of the link pipes is carefully engineered to maximize gas flow without compromising ground clearance or interfering with suspension components. By removing restrictions that limit the stock exhaust, Akrapovic can create a cleaner path for gases to exit, which not only improves peak numbers but also helps the engine breathe more freely across the rev range. Combined with the Slip-On, this upgrade transforms the GT4 RS into a sharper, faster, and more responsive machine, tailored specifically for track environments where every fraction of a second matters.
To give drivers ultimate control, Akrapovic offers an optional Sound Kit. Installed in conjunction with the exhaust parts mentioned above, this electronic controller allows cockpit-adjustable sound modes. A quiet setting is perfect for city driving, while a more aggressive mode unleashes the full fury of the GT4 RS at wide-open throttle. The system integrates seamlessly, maintaining OEM-level usability with Akrapovic’s racing pedigree.
Every component in this lineup is produced through Akrapovic’s advanced in-house processes, which include an R&D department, metallurgy labs, and their own titanium foundry. The materials are inspected with rigorous standards before being formed into parts capable of withstanding the harshest racing environments. The result is an exhaust system that balances lightweight construction, durability, and acoustic brilliance.
The Akrapovic Titanium Slip-On Race Line Exhaust, Titanium Link Pipe Set, and Sound Kit for the Porsche 718 Cayman GT4 RS are available now at Bulletproof Automotive. With their blend of power, weight reduction, and sound quality, these upgrades stand as the definitive exhaust solution for Porsche’s most track-focused Cayman.
