I purchased some cans from these guys via eBay Australia ( http://dominator-wydechy.pl/en). So, they're a lot closer to you. The sound is great! They're lightweight, so that means they're not so robust. But, cheap! I think landed in Aus for around $400 the pair. I should add that I had no difficulty fitting.

They've also used the pic I took after fitting (the XTR here is my bike http://dominator-wydechy.pl/en/yamaha-gid-11.html) and I don't have any affiliation.
