One remote, two states
Press the button and there are only two states to think about:
ON
Valves are held fully open, all the time, in every drive mode. no more waiting for Sport+ to hear it.
OFF
Control goes straight back to your car and the valves run exactly as they did from the factory. OFF doesn't force anything shut! it just hands control back.
How It Works
Take control of your exhaust note
Many modern performance cars come from the factory with electronically controlled exhaust valves. These valves open and close automatically based on your drive mode, throttle input, and RPM — built to keep things quiet for daily driving and only let loose in Sport or Sport+ mode.
The problem? You don't get a say. Want the full exhaust note while cruising around town in Comfort mode, or want to keep things quiet on an early morning start even in Sport mode? Stock, that choice isn't yours to make.
What a VALVD controller does
Each VALVD Exhaust Valve Controller is built to plug directly in-line with your vehicle's factory valve actuator wiring — no cutting, splicing, or permanent modification required. Once it's installed, you decide when the valves open and close, independent of your car's factory drive-mode logic, using the included remote.
Plug-and-play, fully reversible
Because the controller sits in-line with the factory wiring rather than replacing or reprogramming anything, it doesn't touch your ECU or engine tuning. That means no fault codes, no check engine light — and it's reversible any time by simply unplugging it and reconnecting the factory harness.
