Default Universal Expansion Chambers

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

The idea is, you just cut the can off your existing pipe, slide on my chamber and clamp it on to your header pipe.

I'll be making some straight ones, and some angles ones to fit a variety of bikes. Some bending of your header pipe may be required.

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:
