Valvetronic Designs Audi R8/Lamborghini Gallardo/Huracan Exhaust Valve Controller
This controller gives you complete, on-demand command over the factory exhaust valve on the Audi R8 and Lamborghini Gallardo/Huracan family. Unlike a simple on-demand valve delay, it overrides all factory valve function for two clean modes: 100% valves open for maximum sound, or 100% valves closed for a quiet ride.
Installation is plug-and-play with no cutting, splicing, or permanent changes to the car, and the connection is fully reversible, so you can return to a completely stock setup at any time. It also works alongside aftermarket exhaust systems that retain the factory valve controller.
Important Compatibility Information
Fits Audi R8 V8 and V10 (2008-2020+), Audi RS4 B8, Audi RS5 B8.5, Lamborghini Gallardo (2009-2013, all variants), and Lamborghini Huracan (2015-2020+, including EVO, Performante, and STO). On certain Huracan models the OEM exhaust valve solenoid's polarity is reversed from earlier cars; if the controller doesn't respond, the pins inside the connector may need to be swapped, and STO/EVO models are the most likely to need this. The controller also ships with the end connector unplugged so you can confirm power with a test light before committing, since the connector is difficult to unpin once seated.
Features
- Plug-and-play installation with no wiring modifications
- Takes full command of the factory exhaust valve, overriding stock function
- Compatible with aftermarket exhaust systems that retain the factory valve controller
- Two simple modes: fully open for maximum sound, fully closed for a quiet ride
- 100% reversible; return to a fully stock exhaust valve setup at any time
What's Included
- Exhaust valve controller unit
- Wiring harness
- Remote control
Installation Notes
Test the connector's power and polarity with a test light before crimping it in place. Once the connector is pinned, it's difficult to undo, and certain Huracan models (especially STO and EVO) may need the power-side pin swapped due to a factory solenoid polarity change.

Frequently Asked Questions
My Huracan STO's controller isn't responding. What's wrong?
Certain Huracan models, especially STO and EVO, use a factory exhaust valve solenoid with reversed polarity. Swapping the pin on the power side of the connector typically resolves this.
Can I still control my valves if I have an aftermarket exhaust?
Yes, as long as your aftermarket exhaust retains the factory exhaust valve controller, this unit will still give you full command over it.
Is the installation permanent?
No. The controller is fully reversible, and the car can be returned to a completely stock exhaust valve setup at any time.
Why does it ship with the connector unplugged?
This lets you confirm power and correct polarity with a test light before crimping the connector, since it's difficult to undo once it's fully pinned.
