The optional Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovič technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller or the new smartphone app (for iOS and Android) to regulate the valves.

If the car is not equipped with Porsche performance exhaust and you want to use the Akrapovic sound kit than Akrapovic sound kit P-HF1003 with Actuator set P-HF1006 has to be ordered.

If the car is equipped with Porsche performance exhaust with electric valve actuators than actuator set P-HF1006 is required and the Akrapovic sound kit P-HF1003 can not be used. The valves are opened or closed with the valve button inside the car.

When fitted with the optional Akrapovič Sound Kit, ECE type approval is no longer valid.

About Switchable Silencers / Mufflers

Porsche Switchable Silencers & Mufflers - Dual-Mode Performance Exhaust Systems

Switchable Silencers / Mufflers offer Porsche owners the best of both worlds—refined, road-friendly exhaust sound when cruising, and an aggressive, performance-focused tone at the touch of a button. Using valve-controlled technology, these exhaust systems allow drivers to switch between quiet and sport modes, delivering enhanced sound, performance, and driving engagement on demand.

Available from Design911, Porsche switchable silencers include both genuine Porsche-engineered systems and high-quality aftermarket performance options, all designed to integrate seamlessly with your vehicle’s existing exhaust components and control systems.

What Do Switchable Silencers / Mufflers Do?

Switchable silencers use internal exhaust valves to control sound level and exhaust flow.

Core Functions:

  • Allow selectable quiet and sport exhaust modes.
  • Improve exhaust gas flow under performance driving.
  • Enhance throttle response and engine efficiency.
  • Maintain refined sound levels for everyday driving.
  • Deliver a more engaging driving experience on demand.

These systems adapt your Porsche’s character to suit any driving situation.

Why Do Standard Exhaust Silencers Fail or Fall Short?

Factory exhaust systems are designed to meet noise regulations and long-term durability requirements, which can limit performance and sound. Common issues include:

  • Internal corrosion from heat and condensation.
  • Restrictive baffling reducing exhaust flow.
  • Fixed sound levels with no adaptability.
  • Valve or actuator wear in older switchable systems.
  • Limited performance compatibility with tuned engines.

Over time, standard silencers may lose efficiency, sound quality, or reliability.

Why Upgrade to Switchable Silencers / Mufflers?

Upgrading to a switchable exhaust system enhances both performance and versatility.

Upgrade Benefits:

  • Dual-mode exhaust sound at the press of a button.
  • Improved exhaust flow for better performance.
  • Sportier, more engaging exhaust note when desired.
  • Maintains comfort and compliance in quiet mode.
  • Ideal for road, touring, and spirited driving.

Whether OEM or aftermarket, switchable silencers offer flexibility without compromise.

Highlights

  • Porsche switchable silencer and muffler upgrades
  • Valve-controlled exhaust sound adjustment
  • OEM Porsche and premium aftermarket options
  • Improved performance, sound, and driving engagement
  • Compatible with factory systems and controls
