Hey man welcome! Congratulations on your new car. I think you should keep it stock for a bit. Take some time to get used to it before you start switching things up. After you do, make sure you have a vision of what you want the car to be and that of course is determined by what the primary use of the car is, your budget etc. These cars are pretty good from factory, but better tires make a huge difference in how it feels. If you want a bit more power, catless headers and tune will get you that. There is an enormous amount of aftermarket support for this platform so just do some research and see what you like. There's plenty of info here as well. Good luck
