Akrapovič Slip-On Race Line, titanium – Porsche 718 Cayman GT4 / Spyder / Cayman GTS 4.0 / Boxster GTS 4.0 – early 2020 brackets
Akrapovič develops materials, construction and sound as one complete exhaust system. Its development work refines both gas flow and acoustics, with demanding cast components produced in the in-house foundry. Futurez has proudly served as an Akrapovič importer for more than a decade.
The titanium assembly contains two side silencers and a central silencer. Selected titanium tailpipes are included. Porsche changed the mounting brackets around February 2020. Confirm the actual bracket version and choose S-PO/TI/18 or S-PO/TI/18/1 accordingly. Model year alone is insufficient. The matching optional link pipe is L-PO/T/13. Measurements were taken on a Cayman GT4 OPF 2020.
