Enhance Your Audi TT S / TT RS Exhaust Sound with Our Plug-and-Play Valve Controller Unlock the full soundtrack of your Audi TT S or TT RS with our premium exhaust valve controller , engineered to keep the exhaust valves open throughout the entire rev range – from idle to redline. Unlike the factory calibration, which closes the valves at lower RPMs to meet EU noise regulations, our controller delivers a deeper, more aggressive exhaust note 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• Retains full factory Audi exhaust valve functionality• Remote-controlled operation• Discreet installation How It Works The system consists of a bespoke wiring loom that connects directly to the factory exhaust valve actuator connectors, 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 Audi OEM exhaust behaviour with no change to factory operation. Vehicle Compatibility • Audi TT S (8S)• Audi TT RS (8S)• OPF / GPF-equipped vehicles supported• Factory performance exhaust systems supported Installation Support A step-by-step fitting video is available to guide you through the installation process.
