Just bumping this to shout out Dynatech as I haven't seen them mentioned. They also make headers for GEN6 Camaros. Most people I've talked with that had them on whatever vehicle they had them on (mostly GEN2 Lightnings) really had good luck with them and were happy with them.
In the pecking order from high-end to low-end in the Header world I think of them as middle of the road. If ARH/KOOKS/Stainless Works are your high-end headers and OBX, TSP, and other Chinese headers are your lower-end then headers from companies like Hooker Headers and Dynatech are the middle class headers. Dynatech claims all their headers are made in Indiana from 304 SS, but they're noticeably less $ than ARH/KOOKS/Stainless Works. You can get them with either 1 7/8" or 2" primarys.
