SLP is coming out, at the end of March they tell me, with a long tube header in coated stainless 409 with the average length primaries of 25 inches, according to their spec sheet. They will come with a 3 inch stainless collector as well. A y-pipe, which includes a balance tube, is included.
Retail pricing on the headers alone is $1059.95. Expect any discounts from that figure.
When I get more info, I will be sure to post it. Looks like more options showing up every day now.
I also talked to another group yesterday who started the ball rolling on making a 1 3/4" stepped to 1 7/8", stainless or coated mild steel offering very soon. More on that as it develops.
