Not w/o making an adaptor for the flange that connects the header to the cat.. They're different on Contours, Focii, and ZX/2's.
There was someone several months back that claimed to have put the JBA header on his Contour. He had a machine shop make up the adaptor; he didn't mention any clearance issues (not that there aren't any, he didn't mention them).
Terry Haines says he has a 4-1 race header for the Contour (it gets rid of the cat), but haven't seen pictures nor pricing on it.
