(Now I can't remember where I saw those prices or what exactly I was looking at - are you seeing something else? Their website is hard to navigate and the most recent update is 5 years old....)

I don't know where you got that pricing either, but seems higher than reality. The muffler pricing hasn't been announced yet and there is no down pipe for NA cars, so... really don't know where you got that number from.
Looking at the design of things, I suspect the HP gains in the 128 will be had from headers and the sound gains will be had from muffler. The mids are likely fine as is. The stock mids also have secondary cats in them, which is great-- it means you can run aftermarket headers without being overly smelly. If you combine it with a tune that turns off the post cat 02s and still leaves them showing as ready (such as Evolve) or run sims/angulators, it's a pretty cost effective way to gain some power
But, yes, SS's stuff is certainly not cheap.
