What This Controller Does
Did you know race, track, or sport modes do not always keep your exhaust valves fully open?
This controller allows you to override factory settings and unlock the full exhaust sound your vehicle is capable of producing when the valve is normally restricted.
How It Works
ON Mode
- Valves stay 100% open in all drive modes at all times
- Bypasses the vehicle’s factory exhaust control system
- Prevents exhaust valves from closing
OFF Mode
- Valves return to normal factory operation
- Vehicle regains full control of exhaust valve behavior
- Does not force valves closed
Key Benefits
- Instant exhaust sound enhancement
- Full manual control of exhaust valve operation
- Seamless switch between stock and performance sound
- Memory function included in NEW V2 version
- Maintains factory valve system integrity when turned OFF
