for a sti 7 uk, ive been on tsl's website and they recomend replacing the mid section and back box but leaving the downpipe to help with back pressure ????
pete from scoobysport recomends changing the whole lot, ive previously had full ss systems on a p1 and a my97, i liked the idea of leaving the downpipe as its less hassle, and money

Mark I've got the full ss system on but I am going to take it off soon for my PPP, the backbox is going to be replaced by a Blitz NUR spec to anoy my neighbours that little bit extra you are welcome to have a go in it before I take it off if thats any help to you.
