hey there grey take a chill pill bud, A little touchy for it being so early in the afternoon. I said, "I could be wrong". The last Aussie YZ I saw a picture of had a Euro exhaust, and they aren't getting the shorty this year according to some photos that have been posted here. Guessing the same would be true this year did pan out for me. The political issue you brought up is an unforgivable snafu, but it's your organizer's fault, not Yamaha. New stuff comes out all the time. Sanctioning bodies should be ready to deal with it ahead of time. Besides, in that situation, you're more or less forced to replace yours. Our circumstances are different. The pipe's totally legal, it's short, it's light, and it's quiet. Everybody ought to want it. But it costs too much power to keep. The problem is that it didn't have to be like that. There are better ways to build mufflers than that, and I don't believe that Yamaha doesn't know it.
