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 (already included in evolution system) 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.
With the use of optional Akrapovič Sound Kit, the ECE homologation is not valid anymore.

This stunning system is made completely from high-grade titanium. It includes parts cast in the company's in-house foundry, featuring an additional pair of exhaust valves behind the rear mufflers, designed to provide optimal control of the exhaust sound for the best aural enjoyment. The system has been perfectly tuned to deliver the very best sound experience in all modes – enormous effort was invested to give it a rich higher-frequency V6 sound with a sporty racing note, while keeping it smooth and eliminating any drone for maximum everyday comfort. By using the optional Akrapovič Sound Kit, the driver can choose between a loud racy sound or a quieter note for long-distance driving, regardless of the mode chosen for the vehicle. The look of the Slip-On system can also be further enhanced by adding four round titanium or carbon-fibre tailpipes.
An increase in performance and torque through a broad rpm range and a significant weight savings makes this a very serious performance upgrade. With optimized gas flow and reduced back pressure, it allows limitless tuning options.
It is a simple plug-and-play installation with no need for remapping. The exquisite Akrapovič Slip-On Line (Titanium) exhaust system adds performance and style, along with an amazing soundtrack inside and outside cabin.
Fittment notice: This system does not fit on vehicles equipped with Otto particulate filter (OPF). This product will not fit on Executive models and on vehicles equipped with Porsche non-sport exhaust system.

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.
