Kooks headers 50 state legal?

[05blackstang84]

I live in CA and want to install the kooks headers with catted x-pipe on my 2005 mustang gt and would like to know if they are 50 state legal? I've heard because the long tubes changes the original placement of the cats it will fail the visual inspection. Is this true?
