That's the one. When I got mine they had $25 off, now I guess it's $10 off. Still an amazing price for OS quality.
It's great for buggy or truggy. I'd suggest the JP-1 pipe if you're using it in a truggy - the engine has lots of high end power and that pipe gives a little more low end than the JP-2 or JP-3. In a buggy the JP-3 seems to be the pipe of choice.
