The Akrapovic P-HF1433 Sound Kit gives drivers cockpit control over the exhaust note of selected Akrapovic performance exhaust systems. Designed for compatible 2022–2025 Audi RS 3 (8Y) Sportback and Sedan applications, this optional kit uses Akrapovic technology to let the driver switch between a quieter exhaust setting and a more aggressive sport sound.

The system operates through a receiver and valve actuators that open or close the exhaust valves at the outlet of the system. The receiver is already included with the compatible Akrapovic Evolution exhaust system, while this optional kit adds the Sound Remote Controller needed to regulate valve operation. This allows drivers to adjust the exhaust character according to driving conditions and personal preference.

Installation should be performed with the compatible Akrapovic exhaust system and according to the manufacturer’s instructions. Once the optional Akrapovic Sound Kit is installed, the ECE type approval for the exhaust system is no longer valid. This product is intended for automotive applications and is not CARB approved.
