The fabricator requests to be kept private due to the large influx of phone calls. They build headers for select race teams and companies, but generally doesn't do stuff for the open public.
Not a secret, just a source we searched long and hard for, and we want to keep a good relationship with our supplier.
As far as the public is concerned, ATS makes the headers. If you want a set for a particular application, we can have them made. I'm apt to use Shane's 70 Chevelle to make the next set.

Again, hard to say since each header will be completely different in terms of tubing diameter, materials, and options. I'll have a much better grasp of our general price range on these after the SEMA show.
