does the h pipe have to match the headers

im buying a set of long tube headers that are brand new but they are used and the buy doesnt remember what brand they are. they look a lot like super comps but im not sure. im just wondering what brand of h pipe i can buy. does it have to be the same manufacturer as the headers or can it be differant. if it has to be the same can someone tell me where to get the hooker h pipe that does with the supercomp 1 5/8 long tubes. thanks
