I have a 2004 mustang gt and want to know what off road x-pipe, what brands, fit the pypes long tube headers??

I think all will fit your application. I dont know what the connecting flanges on the headers look like, but im sure any would due. As long as you order a "shorty" x pipe. The slp x might not fit. this is the only one that comes to mind that is a little diff i believe.
Call who ever you ordered it from and ask them what brand they would recomend.
