Time To Upgrade

I have a 2000 Galant 3.0 6 cylinder and now that I am out of debt with the parentals, I am not turning my money to my car. I need help from people on what to buy to improve the performance of my car. I have no clue on how to do this and this is why I need your help. If you could just give me the names of things to help and if you know where i could find them. I'm looking for anything so whatever you know that will help, lemme know. Thanks
