No, the flex pipe is just a woven pipe that can bend, the Main cat is always behind the flex pipe.

It goes like this: Headers->Y-pipe->Flex pipe->Main Cat->catback






that is only partly true for a duratec, you are speaking of a atx duratec or a late 99 or 00 SVT

in most 5spd duratec it is Headers->Y-pipe->Main Cat->catback

and zetecs are

Headers->cat/flex pipe->catback
