There are so many riders and customizers bent on changing the R18 exhausts system, I hope that someone will remove the stock mufflers and not want to keep them in storage. I have some ideas to modify them that will require a pair of donor mufflers. The result may end up as junk in the dumpster, if it doesn't work out. But only a pair of OEM mufflers to experiment with will tell the tale. If anyone has a pair in good condition that is just going to collect dust, please let me know.
