Enhance Your Porsche 911.1 GT3 / GT3 RS Sound with Our Plug-and-Play Valve Controller

Unlock the full soundtrack of your 991.1 with our premium exhaust valve controller, designed to keep the exhaust valves open throughout the entire rev range – from idle to redline. Unlike the factory calibration, which closes the valves below ~4,000 rpm to meet EU noise regulations, our controller delivers a consistently more aggressive and engaging sound whenever you want it.

Key Features

• True plug-and-play installation
• No cutting, splicing, or permanent modifications
• 100% reversible – return to OEM at any time
• No need to jack up the car or remove wheels
• Retains full factory Porsche Sport Exhaust functionality
• Remote-controlled operation
• Discreet installation within the engine bay

How It Works

The system consists of a bespoke wiring loom that connects directly to two factory connectors in the engine bay, a compact control module, and a remote handset. Installation is straightforward and completely non-invasive.

When the controller is activated, the exhaust valves remain open across the full rev range. When switched off, the vehicle reverts to standard Porsche OEM PSE exhaust behaviour with no change to factory operation.

Vehicle Compatibility

• Porsche 911.1 S
• Porsche 911.1 GTS
• Porsche 911.1 GT3
• Porsche 911.1 GT3 RS
