i know its the long route but i found a second hand wr 250 tail pipe will fit with some pipe mods easy job if you have a grinder and a welder or know someone, i found that wr pipes are easier and cheaper to get hold of. hope this helps. keith.
I will pass this information on to a friend, Dave. Does it have the complete tail pipe insert? (It seems that there are a lot of mufflers out there with this part removed.) Newbie's latest photo set shows a North American bike with a complete muffler tail pipe.
