Yep, old junkyard replacement might be easier unless you live in a remote location where that stuff is harder to come by than your time to weld it up and fix it yourself. Your choice.
That was the plan, I found one one ebay however I dont want to pay a hundred bucks plus shipping for it. I'm not sure what other machines share the same pipe or one that will work which makes searching difficult.Personally I would be looking for a pipe you can find them used at a lot of salvage yards and with swap meets "hopefully" coming back this fall then you can find on there. Also check facebook, craiglists, ebay and so on. There is a lot of people out there parting out old snowmobiles.
