NEW STAINLESS HEADERS FOR 96 ZX-7R

hey guys and girls, can anyone tell me where i can buy new stainless headers for my zx7 in aus? have found in U.S but would prefer to keep my dollars in aus and support local business if possible. or will i have to get them custom made? also i've noticed that the oem headers have a pipe that is attatched horizontally across the front, what is this for and if i get a set of custom pipes made do i need it on them? any info or advice would be appreciated
