2004 Mustang GT.

Hello, since I'm new here I thought I would post a picture of my Mustang. I just got it a few weeks ago and I love it. It is a 2004 GT, and it is an automatic transmission. Also looked up the rear axle code and I have a 3.27 Trak Lok rear. I am new to the modular v8's, so I have no idea what kind of mods to start with. If anyone can help me out I would appreciate it. I also plan on doing forced induction later, so I plan on doing some mods a little at a time.
