Interchangeability of Fox and Sn-95 parts

Well i have a question on some exhaust stuff and a driveshaft, I am going to have to replace the driveshaft, the H-pipe, and the catback etc. My question is going to be which of these parts will interchange between the fox bodies and the sn-95 models. I know some headers will interchange between model years, and i am assuming that many of other things will interchange as well. but i want to put an x-pipe in the car i am also wondering if that will change anything as far as fitment goes.

thanks
