X pipes vs H pipes, what to use for a dual exhaust conversion

Im going to be changing my 1988 Cougar's single exhaust to a dual, whenever I get atround to it, and i want to know if parts from a fox mustang (header, ler, pipes) will work on mine, cause no stores carry cougar parts. If i could id just go buy hedman headers and flowmaster lers fit for a mustang and use mustang dual pipes the rest of the way. If not i guess id have to bend my own, and find someplace thats ells cougar headers. Also i keep readin about these X and H pipes...whats the difference between them, and why does having both pipes joined improve horsepower?
