Technology
The Nomad uses advanced electronic components to deliver optimal performance, sound control, and street-legal compliance.
1. Modeswitch
The handlebar-mounted, weather-resistant Modeswitch lets you change sound modes at the push of a button.
2. Smartbox
The Smartbox is the control center of the system. It reads signals from the motorcycle’s ECU and automatically adjusts the exhaust when needed to maintain street-legal operation.
3. Servomotors
Once a mode is selected, the Smartbox sends a signal to the servomotors, which move the valve into the correct position for Dr. Jekill, Dynamic, or Mr. Hyde mode.
4. Valve
Our patented valve system controls exhaust flow and delivers the sound mode you choose.
