td-20 tuned exhaust

[dagansen]

I have a 1946 Johnson TD-20 5 hp motor, of almost no financial value, and for laughs I was going to put tuned exhaust on it. However, I have absolutely no idea how to do this. Can anyone here help?

Well you sure picked a difficult one to do it on, what with the carburetor/intake manifold being integral with the exhaust cover.
