Start with this $50 pocketbike pipe:
47cc Full Fairing Pocket Bike Performance Pipe

I got mine from Myers Racing 1-800-797-5955

The new included manifold fits perfect, no mods needed.
Pipe will need 3 cuts, but no bending needed.
I had a header pipe extension MIG welded on, and extended the stinger to the silencer.

The pipe is nicely tucked way out of the way.

Best of all the engine nows revs freely and can pull the mt. hills here with ease. Sounds good too!

As you can see in the photos, it is held securely on with a spring and one bolt. A simple "U" bracket needs to be made but bolts to the stock kickstand hole and the other bolt thru the stock bracket on the pipe. Neat and cleanly done.
