I tweaked your title from "Help Newbie Build 9th Gen Coupe Si" because you're seeking advice not dire help. That word is vastly misused so it just wont help you so keep that in mind for future posts. Keep your titles short, pertinent and to the point for best results.
Definitely take everyone's advice in here. Do heavy research before choosing any options as you clearly lack a lot of the basic knowledge to make well informed helpful choices. Get familiarized with the engine options and colloquial terms. Otherwise, its like going clothes shopping when you don't even know what sizes mean and asking for "leg cloth wraps" when they're called pants, or not knowing that jeans are pants as well. Go through old threads and read up in the "forced induction" section to learn plenty. In my opinion, you're years away from making such choices. To do so with lack of proper knowledge opens you up to wasting money doing things improperly and potentially damaging your engine. As your engine needs maintenance, research your best options and build off that. For now, get a drop-in K&N air filter and a quality exhaust then enjoy them as you learn. Of course, its all up to you but paying for a knowledgeable mechanic to choose your best options is nowhere as fulfilling and figuring it out for yourself first. Good luck!
