Thanks Onno! I ran it on Sunday so it's no longer a shelf queen.

The exhaust was super loud but I was in a park away from any homes! I had all 4 kids with me but they didn't seem to mind the noise!
Hopefully someone comes out with a good exhaust but in the meantime this one will do. With the fuel it's about 30lbs!
If anyone is interested in doing this and has questions let me know.
