What This Controller Does
Factory driving modes such as sport or track do not always keep exhaust valves fully open.
This controller allows you to override factory restrictions and take full manual control of your exhaust sound, unlocking the true tone of your vehicle whenever you choose.
How It Works
ON Mode
- Exhaust valves remain 100% open in all drive modes
- Bypasses factory exhaust valve control system
- Prevents valves from closing automatically
OFF Mode
- Exhaust valves return to factory operation
- Vehicle regains full OEM valve control
- Does not force valves closed
Key Benefits
- Full manual exhaust valve control
- Enhanced exhaust sound on demand
- Seamless switch between OEM and performance modes
- NEW V2 memory function included
- Easy return to factory exhaust behavior when OFF
