Welcome, everything you need can be found on this site. Just pay attention and read.

 

Nice, I'm from Allen, wish I was there now, minus the lovely weather you guys have out there vs over here! lol

 

Congrats, you will love it. Drive it for 10,000 miles to make sure you dont' have any warranty repairs needed, then Hahn/PPC tune (because it is the easiest to quickly install and uninstall), Trifecta would be next since it offers the most power and cool options like one button tune or no-tune, GM stage would be third choice since it is the most hassle and cost (although it does not void warrranty) then Intake tube upgrade, then IC. Then Cat-back, then downpipe with or without CAT depending on where you live, and personal opinion. IMHO.
