We are heading to Asia next month on a F650GS and a Dakar. We have put Staintune exhausts on our bikes. Look at the F650.com website. They talk about doing things to the exhausts. My father in law tried to take it out of his Dakar but failed and has had a staintune put on. Have been told that the cat will not last long with leaded fuel but there are people riding around the world with them . Don't think this has been much, try F650.com
