Welcome back to the forums Nick. I saw you driving around a week ago. You should check out my car now. Basically almost all the bolt ons with my new 3L.
I think you should just do the 3L first. The gains are so much more impressive than anything else. I did it in a couple weeks. It just gets expensive when you do all the extras.
But if you want to stay away from the 3L right now then you should get intake/exhaust setup.
