I put the storz high bub dirt track style pipes on my 09 nightster ,they were expensive but they look good ,sound good and perform great with the stage 1 kit!! i`ve had alot of people compliment me about how good they look ,similar to the xr-750 pipes.the only down side is that you can`t put forward controls on the bike.but i didn`t want to put the forward contols on any way to keep that flat tracker look !!
