HI. I recently purchased my 1st Triumph and am new to your forum which I enjoy visiting. My bike is a 2009 EFI America that has an air injector removal kit and the long TOR mufflers installed. Bike runs great and for me it's about perfect except for the exhaust noise. All my bikes in the past have been stock and quieter and thats what I'm used to. Does anyone know if the EFI settings would have to be changed on the bike if I put stock mufflers back on? If so is that something only a dealer can do? Thanks for your input, Steve.
