2x CARGRAPHIC ID42 GT manifold set with ID 42mm primaries and enlarged 2,5" / 63,50mm flared end collector boxes
CARGRAPHIC with / without 2x100 cpsi Ø110mm MS catalytic converters link pipe set with integrated exhaust valves pressureless closed (PLC)

2x CARGRAPHIC sport tailpipes 122x85mm, oval design, slash cut, rolled in - mirror polished
Fitting kit including gaskets, bracket and bandstraps
SOUND / SUPER SOUND / SUPER SOUND PLUS Version
NO DRONE OR RESONATION even in combination with other CARGRAPHIC exhaust components fitted.
Key Features & Benefits:
- Absorptive silencer design with CNC mandrel-bent pipework
- Fully made from SS304L lightweight stainless steel
- High performance components, dyno tested
- OE / factory heating system retains full functional
- Olive-/ Bandclamp- and sleeve connections enable easy installation and perfect adjustment
- Collector boxes and AQ silencer inlet flanges positioned max to the outside to achieve max possible clearance to valve covers, because of heat radiation.
- Reinforced laser-cut brackets
- Reduced backpressure due to freer flowing
- Reduced operating temperature
- Maximized performance
- Improved throttle response, freer revving
- Improved enhanced acoustics with no drone, resonation or vibration
- New designed Ø2,5" / 63,50mm exhaust flaps are pressureless closed (PLC) which means the car will start quietly (whereas the ordinary version needs intake vacuum to close the flaps which always takes quite some time and can be annoying)
- With flaps closed the gases flow, via the bypass pipes, silenced through the final silencer, whereas with flaps open most of the gas stream flows freely through a second exit within the tailpipes.
- The sound is reminiscent of the famous and legendary RSR`s, simply breath taking!
- Model specific tuned sound still in keeping with the Marque
- Weight reduction
Why Choose This Exhaust System?
The original exhaust on older 964 models can be restrictive in flow, heavy, and produce a muted sound. Switching to this CARGRAPHIC system unlocks the engine’s full potential: better exhaust flow, sharper throttle response, more pronounced exhaust tone, and improved performance — all while retaining reliability and proper fitment. It’s an ideal upgrade for enthusiasts seeking classic 964 sound and performance without resorting to race-only systems.

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.
