I'm doing a 103 upgrade with either SE 255 or HQ 500 this winter. I currently have the SE II slip ons/stock headers. I've heard that the 103/225 is louder. Does anyone have the SE II (old SEs) slip ons with a 103" and if so, are they too loud? I like the sound right now, but will I need to get quiter pipes? Don't want them too loud (that's subjective) but would like to hear my tunes (Ultra Classic) when cruising.
