Description
Unlock the full potential of your Audi RS4 (B9) exhaust system with the 11MODE Exhaust Valve Controller. Designed specifically to suit Audi RS4 (B9) models from 2018 to present, this plug-and-play controller allows you to override the factory exhaust valve behavior and take control—loud when you want, quiet when you need.
Fitment:
- Compatible with Audi RS4 (B9) models from 2018 to present
- For vehicles equipped with dual-valve systems, two controllers are included (left and right—interchangeable)
- For vehicles with a single-valve system, only one controller is required
Key Features:
- True Exhaust Valve Control: Factory modes like Race, Sport, or Dynamic don’t keep valves fully open—11MODE does.
- Wireless Remote: Open or close valves at the press of a button—no wires, no hassle.
- Plug-and-Play Installation: No tools required. Installs in minutes.
- Reversible Mod: Easily removable. Just unplug the device to return your car to stock.
- High Compatibility: Designed specifically for the Audi RS4 B9 platform.
How It Works:
- OPEN / 11MODE (∿): Bypass the factory ECU and keep valves fully open at all times.
- CLOSE / QUIET (—): Restore OEM control, allowing the ECU to manage the exhaust valves automatically.
What’s Included:
- 11MODE Exhaust Valve Controller(s) – one or two depending on your vehicle’s valve configuration
- Wireless Remote Control
Installation Note:
We recommend professional installation for optimal performance and to ensure correct fitment.
