Those are the torque loops being installed... then I put on a set of "Dr. Jekill & Mr Hyde" adjustable exhaust pipes https://www.jekillandhyde.com/en/brand-selector



OPEN = sounds like a Porsche on steroids


CLOSED = sounds completely stock


Here is how it works https://www.jekillandhyde.com/en/how-it-works
The heart of the system https://www.jekillandhyde.com/en/the-valve
When you start the bike the valve is always closed. When you push the button on your handlebars once, the valve will open up completely and your exhaust is set in the performance mode. Click it again and the valve fully closes again. When you double click the button, the valve will be opened to 50% and you ride in the dynamic mode*.

*For riders with a blackbox the amount the valve is open is determined by how long you push the button. I have the blackbox system so I can set my exhaust to any note I want
