Further control over the sound of the Evolution Line (Titanium) exhaust system can be achieved by installing the optional Akrapovič Sound Kit. This gives the occupants of the car the option to regulate the exhaust tone by switching between the quiet mode and a sportier sound. This is facilitated through the use of a Sound Remote Controller or the smartphone app (for iOS and Android), which regulates the valves to drive the actuators that open or close them through the use of a receiver in the system.

When fitted with the optional Akrapovič Sound Kit, ECE type approval is no longer valid.

9m Universal Exhaust Vacuum Valve Controller

Take greater control of a vacuum-operated sports exhaust system with the 9m Universal Exhaust Vacuum Valve Controller.

Developed by Ninemeister to enhance the functionality of exhaust valve systems, the controller allows the exhaust valves to be operated remotely using the supplied key fobs. The kit uses a vacuum control module and is designed for straightforward installation without cutting or splicing into the vehicle's factory wiring or fuses.

What Does the Exhaust Valve Controller Do?

Many sports exhaust systems use vacuum-operated valves to change the route exhaust gases take through the silencer. Opening or closing these valves alters the exhaust sound.

The 9m controller provides additional control over this system, allowing the driver to operate compatible vacuum exhaust valves using a dedicated remote key fob.

This is particularly useful for vehicles fitted with a valved sports exhaust where the owner wants convenient independent control of the exhaust valves.

Why Upgrade?

A dedicated exhaust valve controller gives the driver greater control over when the exhaust valves operate.

The 9m system is also designed to minimise installation complexity. Power is supplied through a cigarette lighter adaptor, so there is no requirement to cut or splice into the factory wiring or fuse system.

Kit Includes

  • 9m vacuum control module
  • Two remote-control key fobs
  • Vacuum tubing
  • Cigarette lighter power adaptor
  • High-quality remotes with Ninemeister logo
  • Components required for straightforward connection and installation

Key Features

  • Universal vacuum exhaust valve controller
  • Remote operation of compatible exhaust valves
  • Supplied with two key fobs
  • Simple power connection
  • No cutting of factory wiring required
  • No splicing into factory fuses
  • Ideal for compatible valved sports exhaust systems
  • Ninemeister branded remote controls

Universal Vacuum Exhaust Valve Controllers

A vacuum exhaust valve controller is an ideal addition to a compatible valved sports exhaust, giving the driver convenient remote control over exhaust valve operation.

Rather than relying solely on the vehicle's original exhaust valve strategy, the 9m controller provides a dedicated remote-control solution while avoiding permanent modifications to the factory wiring.

For Porsche owners searching for a remote exhaust valve controller, vacuum-operated sports exhaust controller or universal valved exhaust remote, the 9m kit provides a simple solution suitable for compatible vacuum-controlled exhaust systems.

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
