As an Armytrix fan, customer, or potential customer, you have likely heard of Valvetronic. It's one of the prominent selling features of Armytrix exhaust systems and has shifted the entire exhaust industry towards adopting similar technology in all exhaust systems. The whole point of the Valvetronic system is to give you an option for how loud you want your car to be. If you leave early in the morning for work, you probably don't want your car to be excessively loud, as it will upset your neighbors. Once you're out on the open road or shredding a canyon road, you want to hear those awesome noises your car makes.

The Valvetronic system allows you to switch between being quiet and being loud with the push of a button via the included remote or through the smartphone application; this works by tapping into a vacuum source on your engine and connecting it to the control module. When you press the button on the remote or smartphone application, you are communicating with the OBDII module via Bluetooth. This OBDII module tells the exhaust valve module to allow the engine vacuum to open or close the exhaust valve. You can also set the exhaust valve module to an automatic mode which will open/close the exhaust valve based on predetermined RPM range or throttle position.

Aside from getting a brutal sound with the Valvetronic system open, you can also gain power, especially if your car is turbocharged. Depending on the car, modifications, and tune you have, the valve being open will also the exhaust gas to flow more freely, as it does not have to pass through any muffler. If your vehicle is turbocharged, you may see a slight increase in boost pressure depending if you are running an open or closed boost cycle, resulting in more horsepower.
