Akrapovič Porsche 911 Carrera Cabriolet/S/4/4S/GTS (991.2) 2016-2019 Sound Kit

The optional Akrapovič Sound Kit gives owners of the Porsche 911 Carrera Cabriolet, S, 4, 4S, and GTS (991.2), 2016-2019, genuine, direct control over the sound of their exhaust system from the cockpit. Rather than being locked into a single fixed character, this kit puts that decision back in your hands, letting you switch between a quiet, more restrained mode and a genuinely sportier, more dynamic flat-six note on demand, whenever and wherever suits you, particularly appealing on an open-top Cabriolet where you'll actually hear the difference more directly.

At the core of the system is a receiver, already integrated as part of the Evolution system, which drives the actuators responsible for physically opening or closing the valves at the end of the exhaust. You can regulate these valves in two ways: through Akrapovič's dedicated Sound Remote Controller, a simple, purpose-built hardware unit, or through their smartphone app, available for both iOS and Android, giving you genuinely flexible, on-the-fly control without needing a separate physical remote rattling around in the car.

This is a genuinely popular addition for Cabriolet owners specifically, since dropping the top means you and your passengers experience the exhaust note far more directly than in a coupe, making the ability to dial character up or down on demand even more worthwhile.

Important: using this optional Sound Kit invalidates ECE type approval for the exhaust system it's fitted to. If retaining road-legal type approval matters for your specific market or use case, this is worth weighing carefully against the genuine convenience and flexibility the kit provides.
