Thanks, y'all. Not sure what it was that was on there before--it was a short, fat little thing with no brand markings on it. Almost looked to me like it was aluminum, wrapped with carbon fiber. It wasn't pretty, but I was growing accustomed to the noise. I like my exhaust a little noisy. My VR (little Chinese dirtbike) has a Suzuka on it, whatever that is. It sounds pretty good. My Yamaha FJ1200 has D&D, and it sounds great. Not sure how some of the others sound on a KLR--Arrow, Akrapovic, Yoshimura, FMF, etc. I do know that stock ain't gonna happen. That thing sounds silly, and I don't want to try and find one, anyway.
