I would start off with a cat-back exhaust and a high flow muffler.

You can ditch the stock cat for a high flow cat for more flow and power. If you're doing this, I'd also make the downpipe (from the manifold to the cat) the same size piping as the cat-back exhaust.

What size engine do you have? 2.5" should be good.

True dual exhaust would be hard to do on an Alero, and may not be any better than a single exhaust anyways. It could only be done on the V6. Each bank of cylinders gets it's own exhaust path to the tailpipe.
If you want dual tips out back, you can just run the single exhaust pipe and spilt it to two mufflers and tailpipes, or run a Camaro style muffler that runs one pipe into the muffler and has two pipes that come out for the tips.
Speaking of exhausts, Albino - you get your new exhaust done yet?
