My 93 xr 600r has a pro circuit exhaust with stock header pipe. It's cool, but is really just too loud. I would prefer to be more stealth, rather than turn heads when I cruise through town (plated the " thunderhog" this past summer!). The bike has some mods from previous owner: unifilter, xr's only jet kit, stage one hot cam. It really moves out, and I want to keep it that way. Anyone have any suggestions on how to quiet down this muffler? I want to avoid spending big dollar on a new muffler. I saw a "silencer" in the thumpertalk store. Not sure if it will even fit the pipe, and am a little supect of how much it will quiet the pipe. thanks p.s. the xr600 is an awesome machine!
