Turbo back / Cat back question (for 'o3/'o4,'o4.5 owners)

I am in search for an aftermarket exhaust for my 305 HP 'o4. As I look at all the companies on line, I see the terminology of tubo back and cat back exhausts systems. Do these mean what I think they mean? If so, the 'o3/'o4 models cannot have a cat back, right? Because there was not one there to begin with. The 'o4 model year is a tricky one to shop for, because rarely are the exhausts differentiated, between '04 and 'o4.5, 3.5" turbo to muffler, 4" muff to tailpipe, and the 325 HP motors are 4" "turbo back". Most of (if not all) the exhausts I see advertised call the "'o4" models 4" turbo back, which mine is not. Should owners of a 305 HP just use the 2003 classification to be safe? By the way- I am looking for an relatively inexpensive flow thru system, (muffler or full exhaust), the salt in the winter will tear an expensive one to shreds.
