What class would this be in?

Hello, I am new here but have heard of and been to some SDKA events before. I am now at a point where I am seriously looking at getting into a kart, and was wondering what class this kart I am looking at would be in? Thanks, and here is the link.

You can run that in Formula y/c with the pipe, or in superbox with the can exhaust.
