A little, not the sort of improvement you'd notice or think worthwhile. The rear gear change is probably one of the more cost effective changes for end result. Free flowing exhaust is close. A cam swap is a waste of time early on unless no further mods ever likely and still need to see if it works with whatever gear you go with, some become a real dog when they need higher revs to make the power to get moving. So you really need a plan of what you intend to do or want, and see which can be done in order without having to be replaced several times over and over.
