Cat-back exhaust systems are essentially "full" exhaust systems, at least compared to axle-back systems. Cat-back does not replace your exhaust manifold (header) though.
As our 9th gen section is slacking, I did a search and came across this entire forum section which should help you out:

Personally, I own an Invidia N1 exhaust cat-back, and I'm very pleased with it. It has a deep tone but not very raspy at all. It's a little loud when the car is warming up, but quiets down nicely afterwards.
I actually purchased it from the store that our site admin runs.. I don't see 2014 year listed there, but you can get in touch with
@Jay Jay who may be able to help you out.
