Custom pregen exhaust options

I'm trying to find a source for small diameter pipe, a 27mm-? universal 2-1 merger if such a thing exists. Everything else can probably be dealt with using thinwall emt, a wire feed, and maybe an apprentice with a hand bender but 2-1 collectors smaller than 2" don't seem to be a thing?
As much as I don't believe the stock twin exhaust on a pregen is much of a limiting factor in terms of flow/power potential the weight savings of a 2-1 has to be significant on such a small bike.
