I'm looking for an exhaust system for my 03 GT, today I heard a Stang with exhaust I liked, chased him down and asked him what he had. He said he had a "cobra cross pipe" is this just a high flowing catted X pipe, or is it something different?
I looked under the car and saw that he had Flowmaster 40's and an x pipe.

 

I'm not sure if Cobra is the brand name, but you can find high flow catted x-pipes in Jegs for just about every Mustang.
