After examining the exhaust donuts I see my inside right Y pipe flange is cracked and I will be replacing both with new stainless pipes. Just need to know now how to remove Y pipes. I have everything off up to pipes and exhaust. I took off shroud above exhaust canister. Just need to know how to pull out all pipes from inside tunnell area.

Hi larry,
Check out the 4 stoke side, the link is in the blue tool bar at top. You will have to register there also but you will get a lot more help. Most of us are all 2 stoke guys here. Chris

Super is correct, more info on the 4 stroke forum. I can answer your question though. The headers must slide forward to get them out which means you need to take the flex pipes off the motor to make room. There is also some hardware under the rubber grommets if you haven't found these yet.
