Yes, if it’s a actual stinger exit made to fit a stock fx1 fuel tank. I had one years ago and it fit fine, I didn’t have to trim my hood lip or anything. It did have a slight lean to the pipe side when sitting in the water. But not much, and it never rattled loose or cracked as some stated about the cast protec pipes.
A couple years ago I called Carl at protec and they still had exhaust flange gaskets, carb jets/spring kits for that pipe setup in a fx1
