Just bought and fitted some Leovince X3 exhaust to my xt660r , after returning a set of delkavic and a set of hawk as was not happy with the quality of them. Just in case anyone wanted to know the quality of the Leovince exhaust is up there with the best of them. And come with uk/eu noise legal baffles fitted,and come with two other sets of baffles loud and f loud ( long /short) Mind you the legal baffles are loud enough. There is one company doing a deal on eBay �458 down to �390 And some places still selling them at �498
