A cat-back exhaust replaces the pipes, muffler and tips behind the catalytic converter. This one exits out the side in front of the rear wheel instead of out the back, with twin 4.0in tips.
why this one — The side exit is the reason to choose this over the rear-exit Corsa. It puts the tips where you can see them and keeps them clear of a bumper-mounted hitch and trailer, which matters if you tow. Corsa's Sport sound level and their reflective sound cancellation mean it will not drone at highway speed. Two honest points: it costs about 220 dollars more than Corsa's Classic-body system for a similar package, and side exit is a look you either want or you do not.
