i Thought the whole point of cat back exhaust systems and headers, and a manifold was horsepower. I guess not. Sounds like its all for noise.

you do get gains but depending on what brand, size, etc.. of headers and exhaust system you buy it can vary. You can get significant horsepower gains from replacing your exhaust system but expecting people to be able to tell you exactly what results you will get on your specific car is naive. Most people can tell you a general area of what you can expect with certain mods on a Camaro and not a mustang because this is a Camaro forum.
