Once you tune your engine, the basic x chamber should have a 6" OD belly, with the appropriate diffuser and convergent cones. A KTM 50-80 pipe is about right, but you have to cut and weld to make it work.
I've yet to see a pipe that's not just a re-purposed pocket bike pipe that actually works.

These pipes are pretty good.
you can easily cut the header pipe & make it a little longer (or shorter) to tune it.
