Borla or FA20 header as mentioned, my preference and what I'll go for is the fa20 simply cause it caters to both NA & FI applications by its design. Don't forget companies like Avo Turboworld make 5" high flow catted front pipes so you can go with an un catted header with that option in mind as well as their front pipe also has a bung for your O2 sensor on the front pipe.
And as sports guy mentions you're in the right state, fa20 is right there, give em a call they have everything you need to get pimped out. Hell if I lived where you are, it's honestly a NO BRAINER.
