Switchable Silencers / Mufflers
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.

Designed as a direct bolt-on replacement for the factory left and right valved side silencers, this performance exhaust upgrade delivers a deeper, richer and more aggressive exhaust note while retaining the refinement expected from a modern Porsche Turbo S.
Engineered to enhance the distinctive sound of the twin-turbocharged flat-six engine, the system produces a more engaging sports car soundtrack without unwanted interior drone.
The silencers integrate with Porsche's factory exhaust management system, retaining full OEM exhaust valve control and allowing the driver to enjoy a more pronounced exhaust character when desired.
Manufactured from premium T304L stainless steel, the system combines excellent corrosion resistance, strength and long-term durability with precision construction and a high-quality finish.
What Do the Valved Sports Silencers Do?
The Ninemeister 9m Valved Sports Silencers replace the original left and right exhaust silencers, altering the exhaust sound while retaining the factory-controlled valve functionality.
The revised silencer design allows more of the engine's natural exhaust character to be heard, producing a deeper tone and a more aggressive soundtrack during acceleration.
When the exhaust valves are operating in their quieter setting, the system maintains a more refined driving experience, making it suitable for both everyday road use and enthusiastic driving.
Why Upgrade to Ninemeister 9m Sports Silencers?
The standard Porsche 992.2 Turbo S exhaust system is designed to balance performance, comfort and noise regulations.
For drivers seeking a more distinctive exhaust note, the Ninemeister 9m system offers a noticeable improvement in sound without sacrificing the convenience of factory exhaust valve operation.

- Designed to minimise unwanted cabin drone

Why Choose T304L Stainless Steel?
The silencers are manufactured from premium T304L stainless steel, selected for its strength, corrosion resistance and durability.
Compared with conventional mild-steel exhaust components, stainless steel offers improved resistance to moisture, road salt and exhaust system corrosion.
The low-carbon composition of T304L stainless steel also provides excellent resistance to corrosion around welded areas, making it particularly suitable for high-quality performance exhaust construction.
Factory Exhaust Valve Integration
A key feature of the Ninemeister 9m system is its compatibility with Porsche's original exhaust valve management system.
The replacement silencers retain the factory-controlled valve operation, allowing the exhaust character to respond to the vehicle's existing control settings.
This provides a balance between a more engaging performance soundtrack and comfortable everyday driving.
When Should the Sports Silencers Be Fitted?
The Ninemeister 9m Valved Sports Silencers are designed as a performance and sound upgrade rather than a routine replacement part.
They are ideal for owners who want:
- A more distinctive Porsche Turbo S exhaust note
- Increased exhaust character during acceleration
- A deeper and more aggressive sports car sound
- Retention of the factory exhaust valve functionality
- A premium stainless steel exhaust upgrade
- Improved driving enjoyment without excessive cabin drone
Installation Notes
The system is designed to replace the original left and right valved side silencers using the factory exhaust mounting arrangement.
Installation should be carried out by a suitably qualified technician, ensuring all exhaust connections, mounting points and valve-control components are correctly fitted.
Check exhaust clearances, valve operation and the security of all connections following installation.
Road-use legality, noise limits and emissions-related requirements should be checked for the intended market before fitting.
