thats the one you want, it has the correct O2 sensor flange. the 7afe and 4afe headers are IDENTICAL, stock and otherwise. i had one just like it, it works fine and fits well, but i recomend you heat wrap it since the thinwall stainless puts out ALOT of heat.
that black coating is probably just spray paint and may not even last, heck they could just be covering the fact that its made from mild steel which isnt going to last as long as even low grade 304 stainless.
