Akrapovič Porsche 718 Cayman GT4RS (2022-2026) Slip-On Race Line Titanium Exhaust System

The Akrapovič Slip-On Race Line (Titanium) is a precision-engineered exhaust system built for the naturally-aspirated flat-six in the Porsche 718 Cayman GT4RS, the most track-focused variant in the current 718 lineup, borrowing its high-revving engine directly from the 992 GT3. Crafted entirely from lightweight titanium, this system is designed to let that motorsport-derived flat-six deliver the soundtrack its genuine racing pedigree deserves, enhancing sound, performance, and weight savings all at once.

Complex components, including valve housings and collectors, are cast in Akrapovič's own in-house titanium foundry, a level of manufacturing precision that's difficult to replicate with off-the-shelf mandrel-bent pipework, delivering a genuinely deeper, more resonant tone as revs climb toward this engine's spectacular high-rev character. Titanium construction throughout delivers a genuine weight saving over the factory system, a real, measurable benefit for a car where Porsche's own engineers already went to extreme lengths to shed weight everywhere possible, meaning every additional gram Akrapovič removes is genuinely meaningful rather than incidental.

Finished with hand-crafted tailpipes, this system gives the rear of the GT4RS a distinctive, motorsport-inspired look that matches the drama of the sound underneath, entirely fitting for the most extreme road-going 718 Porsche currently builds.

Optional upgrades available: a matching Evolution Header Set (Titanium) and Link Pipe Set (Titanium) are available for this platform, sold separately, letting you push the performance and sound even further. A Sound Kit and matte carbon fibre rear diffuser are also available.
