I want to buy a racing header, flex pipe and exhaust, but am worried about failing emissions testing in Oregon. Has anyone passed emissions with these Mods? or Does anyone have any suggestions?

Some states don't have visual...here in MO we only get the visual if we fail the sniffer. Putting a cat in the flex pipe should do the trick but remember to have it completely warmed up before you roll in for the test. The further back in the system you put the cat, the longer it takes to get up to operating temp.
