PRODUCT DISCLAIMER
We recommend confirming that your vehicle is equipped with a factory-controlled valved exhaust system before ordering.
Professional installation is strongly recommended.
This product is intended for off-road / track use only where applicable. Installation and use, including use in extreme weather conditions, is at the customer’s own risk. Please refer to our Terms of Service for full details.
Take Full Control of Your Exhaust Sound
Unlock the true sound potential of your Audi S3.
From factory, valved exhaust systems are controlled automatically by the ECU using driving modes (Eco, Comfort, Sport, Race), along with real-time driving conditions such as RPM, throttle input, gear selection, and speed.
Even in Sport or Dynamic modes, exhaust valves do not stay fully open at all times — they continue to open and close depending on driving conditions.
The 11MODE Exhaust Controller removes this limitation and gives you direct control over your exhaust valves.
How It Works
ON Mode
- Exhaust valves stay 100% open at all times
- Works across all driving modes
- Overrides factory ECU valve control
- Prevents valves from closing under any condition
- Delivers consistent maximum exhaust sound
OFF Mode
- Returns full factory ECU control
- Valves operate normally based on driving conditions
- No forced open or forced closed position
Important Note:
This system does not force valves closed, ensuring safe operation under all conditions where the vehicle may require valve movement for performance or protection.
