I'm surprised they didn't kick you off CorvetteForum for buying those!
But seriously, did you look into Texas Speed at all? Their headers are Chinese made, but at least designed with full R&D in central Texas, they just outsource the production to undercut the big American made brands like LG, ARH, Pfadt, and Kooks.
A few years ago I won a set of AFE/Pfadt Tri-Y headers (which were beyond beautiful) but ended up selling them to stick with my ported/coated manifold + Borla X-pipe setup which retains the primary cats for emissions and warranty reasons.
