I'm a contour owner and I'm trying to help the zetec 'tours out. We only know for sure that a kamikaze header will work on a zetec contour (even then with modification, mainly being custom downpipe,flex pipe,etc. and if you have a/c, tapping a new o2 port). anybody here with other types of headers that has access to a contour or just some good knowledge on the matter? it'd be really nice if some other headers work for the contour, so any thoughts?
