So I’m looking to buy a new sled. I’ve been out of the snow machine world for quite a few years but did a lot of riding in my kid years. But the sled I’m looking at starts good Sounds good rides good. But a spot in the exhaust scares me cause I don’t know where it could have came from. Just wondering if the black stain came from something blowing up. Any help would be awesome

To me it looks like blow through from the muffller joint just in front of it. Common for those joints to leak a little. Might have been run without the donut installed too.

I don't think I've ever seen a mount with the exhaust pipe running over the top of the motor. What a terrible design.
