Akrapovič Porsche 911 Carrera/S/4/4S/GTS (991) 2012-2015 Slip-On Line Titanium Exhaust System

The Akrapovič Slip-On Line (Titanium) is a precision-engineered exhaust system built for the naturally-aspirated flat-six across the original 991 Carrera range, covering the Carrera, Carrera S, Carrera 4, Carrera 4S, and Carrera GTS, 2012-2015. This generation still ran the naturally-aspirated engine before Porsche's shift to turbocharging across the entire Carrera lineup, giving these cars a genuinely different, arguably more classically 911 exhaust character than the later 991.2 that replaced them. Crafted entirely from lightweight titanium, this system is designed to enhance every aspect of the driving experience, from sound and performance to weight savings and aesthetics.

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, letting this naturally-aspirated flat-six deliver more of the high-rev character it's genuinely capable of. Titanium construction throughout delivers a genuine weight saving over the factory steel exhaust, a real, measurable benefit for handling response on Porsche's most iconic rear-engined sports car.

Optional upgrade available: Akrapovič's Sound Kit is available for this platform, sold separately, letting you control the exhaust valves independently of the car's drive mode.
