A cat-back exhaust replaces everything from the catalytic converter back to the tips. It changes sound and sheds a little weight - it is not a serious power mod on its own.

why this one — The axle-dump design exits the exhaust in front of the rear axle instead of routing all the way to the back bumper, giving a louder, more unfiltered sound - mainly popular for off-road/trail trucks. SPD does not publish a power figure.
