Just purchased his and hers 2015 Street Glides. She traded in her 2013 Dyna Switch Back and regretfully traded in my 08 Heritage Softail Classic. Had made several modifications to her bike, adding Vance and Hines Monster Duals, tuner and Dyno'd along with adding touring lights and a few other chrome goodies. My '08 was modified with a Woods cam ( 525 lift ) Vance and Hines Long Shots and it sounded good. Now this brings me to my point. Looking for advice on replacing stock exhaust on our new bikes, does it need to be re mapped if head pipes are changed which I may do because heat from rear pipe is above and beyond. I was told this was due to the catalytic converter. Looking for the sound my long shots had. ( not sure if long shots are available for 2015 SG ) Also looking to upgrade speakers in bat wing, any suggestions on speakers? Any advice is welcomed
