Universal Expansion Chambers
I'm making some pipes designed for 50-80cc engines, that are clamp-on universal pipes.

Still in the prototype stage, and I'll be bringing some to the Grange race on april 1st.
Once they're proven on the track, they'll be for sale (and a thread will be posted in the appropriate section.)
Here's a sneak peak:
