In short its an exhaust valve that opens and closes to regulate noise at idle. The valve is known to get stuck open or closed which would throw a code, but now I am confused did you start with a daytona or a striple? the striple did not come with it. So if you have a striple then its something else.
Edit: NVM you are originally a Streety, the TOR tune shouldnt be a problem here since several people have ran TOR tune on a stock setup. It is not optimal and usually people will upload the tune while they are waiting on their slip on to arrive.
