Header Question

I have a machine to do the flanges, and the rest of the equipment to form and weld the tubes.
Just not sure if there would be enough interest in doing them.
As much as I dislike working with it(other than welding), I'd like to see headers made in stainless, shorty or otherwise. There must be a reason they're not popular. Wish I could polish the exhaust instead of de-rusting and painting it
