Then If you are not supercharged and don't want to do a top swap, then go for the k&n cold intake system (about $250-$350) and that will give you like 10-20hp. Or if you want to go all way out, then go turbo (about $4,000) and that will give you 100hp+ depending on stage and configuration. But Never consider an electric turbo since it is a fraud! They advertise a 2-3psi boost but what really happen is that is a 2-3psi restriction with the turbo powered off and normal performance when the turbo is powered on. (Yes you will feel the boost... from restriction to normal!)

Then delete the U-bend on the exhaust, that will give you like 3-5hp. And if you want a nice sound, then go magnaflow or flowmasters (you'll love it, unless you got small kids and a wife then your wife will hate it since is very loud and blah, blah, blah!!) and it will give you like 15-20hp with the U-bend deleted.

Change the ignition coils from stock (rating 15,000 volts) to racing (rating 40,000 volts) all six for $150 in grandprixstore.

Then you can upgrade your suspension to allow the HP to go more freely from your engine to your tires, you'll always loose some HP from the Flywheel to the Tires (from 15-25 % depending on weight and other stuff) but suspension upgrade will help you to not loose that much.

If anything comes to my mind, I'll write later.

Also, remember that when you are installing performance parts to your car you can't expect to be mathematically adding horsepower with every upgrade you install, sometimes 1hp + 1hp isn't 2hp, sometimes it is 1.5hp at the end and sometimes is 1.2hp and so on. All performance upgrades need to be balanced to help each other to increase the expected horsepower.

Anyway, good luck.
