There are many brands of headers......do some searching and view some of our vendor's sites. As for sound, most will sound the same. The difference will be if you go no cats (will sound raspy) or cats (more deeper sounding). Performance will be very close. Yes, if money is no issue, ARH, Kooks and Stainless Works will fit that bill and are of good quality. Stainless works has a budget header (Stainless Power) that are getting great reviews. (They are very nice, just installed a set on a buddies car last week) TSP has nice budget headers. Despite the OBX haters, they do make a decent, inexpensive header (I have them). They are 304 stainless as well. The big issue with OBX is there is speculation they copied Kooks. And lastly, Pacesetter makes good mild steel headers that have a lot of followers. You can get them coated as well.
