Welcome to the forum @robertpaulhill1961@gmail.
So you have a newer untouched bike and merely replaced the exhaust? Are you the first owner? Feel free to add a thread in the New Owner's Forum. The more details that the members have about your bike and your experience the better.
Was the bike professionally tuned, with the fuel map in the ECU overwritten?
