Porsche 718 Cayman GT4 RS | Akrapovic Performance Exhaust Installation

This particular vehicle is finished in a Paint-to-Sample (PTS) colour and equipped with the Weissach Package. Delivered to PERON Automotive’s Performance Workshop as part of our concierge service, this GT4 RS was brought to PERON with the goal of enhancing every aspect of its already exceptional character—from sound and performance to weight savings and aesthetics. 

This unique Porsche was collected directly from the dealership with delivery miles after our client authorised us to liaise with the dealership on their behalf. Using our trusted transporter and fully enclosed trailer, the vehicle was safely delivered to the PERON in pristine condition. As part of our standard process, the car underwent thorough inspections before and after the agreed work to ensure it met PERON standards.

Throughout its journey, our client received regular updates, with photos shared during the installation to help them feel involved and part of the process. This particular client valued being kept in the loop, and we were more than happy to oblige—our commitment to customer service is at the heart of everything we do. Once the work was complete, the GT4 RS was transported once again by our concierge service and delivered to Topaz Detailing for a full Paint Protection Film (PPF) application.

At PERON Automotive, all customer vehicles are stored securely in our climate-controlled, fully insured workshop day and night.

At PERON’s Performance Workshop, the installation of the Akrapovic Slip-On Race Line (Titanium) and Rear Carbon Fibre Diffuser on the Porsche 718 Cayman GT4 RS was as seamless as expected—precisely what we’ve come to expect from Akrapovic. Like every Akrapovic system we’ve handled, the Slip-On Race Line is engineered for superior fitment, ensuring a straightforward installation process. Akrapovic’s meticulous attention to design means every component integrates naturally with the vehicle’s factory setup, aligning so perfectly it feels like an original part rather than an aftermarket upgrade. This flawless integration, combined with the exceptional craftsmanship of both the titanium exhaust and carbon fibre diffuser, enhances the GT4 RS’s performance and aesthetics without compromise.

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. 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.

Expertly handcrafted from race-proven carbon fibre, this rear diffuser is a premium addition to the Slip-On Race Line (Titanium) exhaust system. Available in a matte or high-gloss finish, it complements the exhaust’s tailpipes while enhancing the car’s aerodynamics and aesthetics. Designed with practicality in mind, the lower section features two replaceable rubber protectors to prevent scratches on the carbon fibre during track use. The diffuser also offers a significant weight reduction of 2.4 kg (52.6%), further improving the vehicle’s performance dynamics.

The Akrapovic Slip-On Race Line (Titanium) and Rear Carbon Fibre Diffuser combine cutting-edge engineering and craftsmanship to take the Porsche 718 Cayman GT4 RS to new heights. Designed to enhance sound, performance, and aesthetics, these upgrades perfectly complement the track-focused nature of this iconic Porsche.

From its deep, harmonious exhaust tone to its significant weight savings and precision fitment, the Slip-On Race Line delivers an unmatched driving experience. Paired with the striking carbon fibre diffuser, this setup not only improves performance but also refines the car’s aggressive styling.
