exhaust gains on ka24de

Sorry if this is posted somewhere else but i cant find it.

I am new to these cars and am in the process of purchasing a 95 240sx se. The mufler is the only bad thing on it really and I have decided i will just be swapping the whole exhaust so I can later mate that exhaust up to an SR. Money pending. What gains am I looking at getting out of this and would i get any more by adding in my AFC Select that i have?

Sorry if this is all in here like i said i cant find actual answers anywhere.
