I have just purchased a 2004 XR250L, i have removed the snorkel, and put in a free flowing air filter, however when i went to the exhaust to do the baffle mod, i found that it is different to any of the exhausts mentioned for doing the mod, when i undo 3 bolts at the end of the Can the chrome part comes off, but the baffle looks like it can not be removed, the model number on he Can is HM KCZ K2, has anyone found how to get the baffle out of this exhaust...any help would be appreciated, and yes, i have searched..
