Any point in aftermarket uppipes?

Ok, so I read some threads about people who have installed aftermarket, catless uppipes on their legacy's and noticed a little increase of low end power anda "much welcomed exhaust sound".
The thing is, aren't our stock uppipes catless? What would be the point in getting a new one? The only difference could be pipe diameter right? And if you give it a bigger pipe its just going to slow down the velocity of the exhaust gases and actually slow spool up. Unless the uppipe is too small to begin with and switch to a bigger uppipe actually frees up the gasses a bit more.
Am I correct?
So basicallly, I would assume the only reason to purchase a new uppipe would be to get a larger pipe diameter to flow more exhaust gas. Which would only be effective if oyu also have nice headers and are making enough power to actually necessitate a larger exhaust system form the engine back.
