Experience the unmistakable character of the Porsche 718 Cayman GT4 RS with the Akrapovič Slip-On Race Line Exhaust, a premium titanium exhaust system engineered to enhance performance, reduce weight, and deliver one of the most exhilarating exhaust notes available for Porsche's naturally aspirated flat-six engine. Designed and manufactured in Slovenia, this genuine Akrapovič system combines race-proven engineering with exceptional craftsmanship to create an upgrade worthy of one of Porsche's most focused driver's cars.
Constructed entirely from high-grade lightweight titanium, the Slip-On Race Line Exhaust dramatically reduces overall system weight while maintaining exceptional strength and durability. The sandblasted titanium finish provides a refined motorsport appearance, while the premium materials offer outstanding resistance to corrosion, heat, and long-term wear under demanding driving conditions.
At the heart of the system are two Akrapovič in-house cast titanium valve housings, developed to precisely regulate exhaust flow depending on engine load and driving mode. At lower engine speeds, the system produces a smooth, refined tone suitable for everyday driving. As the revs increase and the exhaust valves open, the sound transforms into the unmistakable high-revving soundtrack expected from the Porsche GT4 RS, delivering a thrilling motorsport experience without unwanted cabin drone.
The beautifully engineered titanium tailpipes feature a coated outer shell combined with an uncoated cast titanium inner sleeve that naturally develops an attractive blue hue after repeated heat cycles. Each tip is finished with a precision laser-engraved Akrapovič logo, highlighting the premium craftsmanship that has made the brand one of the most respected names in high-performance exhaust systems worldwide.
Performance improvements extend beyond sound alone. Akrapovič's extensive dyno testing recorded gains of 5.6 kW (7.6 hp) at 4,950 rpm together with an increase of 19.3 Nm of torque at 2,250 rpm compared to the standard Porsche exhaust system. The titanium construction also reduces overall exhaust weight by approximately 7.6 kg (44.4%), improving handling characteristics and reducing mass behind the rear axle.
Designed as a direct-fit upgrade, the Slip-On Race Line Exhaust installs without requiring ECU remapping, allowing owners to enjoy immediate improvements in sound, appearance, and performance. For enthusiasts seeking even greater performance, the system can later be combined with the optional Akrapovič Evolution Link Pipe Set, Evolution Header Set, and Carbon Rear Diffuser to create the ultimate Porsche GT4 RS exhaust package.
Whether your Porsche is driven exclusively on the road or regularly visits the racetrack, the Akrapovič Slip-On Race Line Exhaust delivers a perfect combination of lightweight engineering, premium materials, and the unmistakable motorsport sound that defines every Porsche GT model.
