There is a square metal plate on each pipe. It says banchee...lol [not banshee] hi rev or mid range and the year they were manufactured... you could try to use your stock silencers they may work, Not sure or your going to have to buy a set of paul turner fatboy silencers new or used.. maybe check ebay if your stockers don't fit. your jetting will be anywhere from a 280-300 and a 25-30 pilot. I would start with a 300 main jet and 27 or 30 pilot jet, start big and work your way down. do a WOT plug chop when you think you have it where you want it.
black and wet = rich, white= lean and choco brown to dark tan is perfect.
good luck
