There are aftermarket exhausts out there, and some of them even have additional accessories that can quiet the exhaust down, but looks like all the aftermarket systems are all about making it louder...I do like my loud V8s in my cars and trucks, but I'm not the biggest fan of the V-twin sound (just personal preference!) with the completely stock exhaust it's loud at idle but on the move it's deafening. I have to wear ear protection! I really like the machine either way and I suspect there might not be many options in this area...but never hurts to ask!
