Alright, went to Port Yamaha yesterday, got my new y-pipe. I got there last 91$ version of the stainless y-pipe. Saving me quite a few bucks. Apparently Yamaha Engineers think the excess donut wear is due to heat and moisture. That new flange on the new y pipes is suppose to keep snow from entering where the y-pipe and flex pipe meet, therefore reducing the wear on the donuts. People with the new pipe will find out I guess.
Put the pipe on yesterday, it went pretty smooth. My sled is seeing the wear of 12,000 miles though. The rivets supporting the pipe bracket for the two y pipes are ovaled out, and that bracket now does nothing. Also broke a head of a bolt, making things more exciting. Just need to put a few panels on and its all done.
