Is there really any noticable differnce from a stock exhaust to a FMF Powercore 2 exhaust? Also is there a difference from a stock pipe to a FMF Fatty Gold Series pipe?

The silencer isnt going to make much, if any, difference. The expansion chamber will shift power around, which may or may not be a good thing depending on the pipe and what kind of riding you do. I'd just stick with the stock pipe unless its dented; in which case he Fatty is a good all around choice.
