Axle backs don't really have any gains at all its just more for the sound and appearance, cat backs give gains through the bigger piping and mandrel bent tubing which improves air flow which gives you more power. I have done both axle backs and cat backs and haven't noticed a big difference with either. If you have the money get the cat back it does add power even if you cant feel it completely.
