Race-Ready Titanium Exhaust Built for the 2022-2025 Porsche 718 Cayman GT4 RS
The Akrapovic S-PO/TI/24 Slip-On Race Line (Titanium) transforms your 2022-2025 Porsche 718 Cayman GT4 RS with a full titanium muffler assembly that sheds 10.5 kg (47%) of exhaust weight while delivering the signature high-revving Akrapovic exhaust note motorsport enthusiasts demand. Developed alongside Porsche factory engineers, S-PO/TI/24 is a precision bolt-on system requiring no cutting or welding, with integrated valved sound control that transitions from a refined street tone to a full-throated race crescendo as revs climb. If you run your GT4 RS on track days or autocross events and demand genuine performance hardware, the Akrapovic S-PO/TI/24 is the definitive choice.

Frequently Asked Questions
Does the Akrapovic S-PO/TI/24 fit both the 2022 and 2025 Porsche 718 Cayman GT4 RS?Yes. S-PO/TI/24 is engineered to fit all 718 Cayman GT4 RS models on the 982 platform from 2022 through 2025. No modification is required for any model year within that range.
Is the S-PO/TI/24 street legal?The Akrapovic S-PO/TI/24 is designed for closed-course competition use only and does not meet street emission compliance requirements. It is intended for track days, autocross, and competition events. Confirm local regulations before road use.
How much weight does S-PO/TI/24 save over the stock Porsche GT4 RS exhaust?S-PO/TI/24 weighs 11.8 kg versus the OEM system at 22.3 kg, a reduction of 10.5 kg or roughly 47%. The weight savings improves handling balance and reduces rotational mass on the 982 chassis.
What power gains does the Akrapovic S-PO/TI/24 produce on the 718 GT4 RS?Akrapovic's own dyno testing shows the S-PO/TI/24 adds 5.6 kW (7.6 hp) at 4,950 rpm and 19.3 Nm of torque at 2,250 rpm compared to the stock muffler. Results are on the 4.0L flat-six engine.
Does the S-PO/TI/24 require an ECU tune or remap?No. The S-PO/TI/24 is a slip-on muffler replacement that requires no ECU remap or engine management changes. It retains full OBD compatibility and installs without software modifications.
Can I add the link pipe set to S-PO/TI/24 later?Yes. The optional Akrapovic L-PO/T/17 Titanium Link Pipe Set is sold separately and can be added to maximize exhaust scavenging for greater power output on closed-course applications. The two systems are designed to work together.
How loud is the Akrapovic Slip-On Race Line on the 718 Cayman GT4 RS?S-PO/TI/24 features dual integrated valves that modulate sound output. At lower revs the note is deeper and controlled; above 4,000 rpm the valves open delivering a full high-frequency race exhaust sound. It is noticeably louder than stock at all RPM ranges.
What is the warranty on the Akrapovic S-PO/TI/24?Akrapovic provides a standard 2-year warranty on S-PO/TI/24. The warranty extends to 3 years when you register the product at akrapovic.com within 30 days of purchase.
Does the titanium finish on S-PO/TI/24 change color over time?Yes. The sandblasted titanium tailpipes develop a natural heat-reactive patina, progressing from silver to gold and blue tones with normal use. This is an inherent characteristic of titanium and is expected behavior, not a defect.
