Get an up-pipe and a down pipe and a high flow cat. That would improve your gas mileage tons. But a full exhaust is expensive and time consuming. I myself just have a cai and i'm putting my slp cat-back on tomorrow. SLP makes the biggest diameter piping without loosing any performance. 2.5 is the biggest you should put on your stock car. That should help yaÂ;-)

generally, what stealth is saying is true... but you have to watch out. Going too big on exhaust and cats and downpipes can actually hurt your gas mileage and horsepower because you lose the necessary backpressure your car needs. You probably wouldn't get much of a power gain with a high flow cat unless you have headers. Catback systems add a bit of horsepower, but not much without headers.
I have also seen the "air tornado" thing on TV. Initially, I (as well as most other ppl on the site) was very skeptical about this... but then I have heard from people who have a lot of experience with intake systems and they have actually been tested to work slightly.

I have the air tornado and will live by this thing, even on the way to GAP me and scott compared rpms and we both have pretty much identical engines (cai 2.4L) and i ran 80mph at 2100rpm he was runnnin 80mph at 2500rpms, so it does help your air flow[/quote]

i had this on my old car... chev lumina 1990 3.1 v6 i had it installed with my custom cai and i swear it helped.. but then i heard all this crap about it just being a joke and it doesn't do poop.. so i figured it was just my cai... and never bothered to get one for the alero... maybe i'll try it out or see if my old one fits..
