IIRC, the Saleen hood that I'm thinking of is basically a stock hood with a mustang hood scoop on it. You can get the same look by getting a hood scoop off a (double check but I remember it being a) 98-02 Mustang. I've seen this done a few times on the focus so I know it does work. I got some pics somewhere, just not sure at the moment right now and sorta in a rush to go out here soon..... I'll check the thread later.
