9m Sports Stainless Steel Valved Silencer
Upgrade the sound and character of your Porsche 987 Boxster
or Cayman with the 9m Sports Stainless Steel Valved Silencer. The valved design gives the driver control over the exhaust
character at the push of a button, allowing you to switch between a quieter
exhaust note and a louder, more sporting tone. 9m also specifies a noticeable
improvement in sports car sound and throttle response.
Fits:
- Porsche Boxster 987 2.7L 2005-08/08
- Porsche Boxster 987 S 3.2/3.4L 2005-08/08
- Porsche Cayman 2.7L 987C 2006-08
- Porsche Cayman S 3.4L 987C 2005-08
Manufactured from precision-welded 304-grade stainless steel, the system is designed as a direct replacement for the original Porsche rear silencer, with no cutting or welding required.
What Does the Valved Exhaust Do?
The exhaust valves alter the path of the exhaust gases through the silencer. This allows the system to provide a more subdued sound when required and a more pronounced sports exhaust note when the valves are opened.
This makes it particularly suitable for a road-going Porsche where you may want a quieter exhaust during normal driving while retaining the option of a more engaging sound when desired.
Why Upgrade?
The factory exhaust is designed to balance refinement, noise regulations and performance. For owners looking for greater exhaust character, the 9m valved silencer provides additional sound without permanently committing the car to a louder exhaust note.
The X-pipe-style system also gives the rear of the car a more purposeful appearance, with a choice of black or silver slash-cut exhaust tips.
Direct Bolt-On Installation
The 9m system is designed to replace the OEM muffler using a direct bolt-on installation, requiring no cutting or welding. This makes it a straightforward exhaust upgrade without unnecessary modification to the vehicle.
9m states that the silencer complies with emissions regulations and does not trigger the Check Engine Light.

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

- 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.
