Inlet Tube with drop in air filter
Lightweight crank, alternator, water pump pulleys
JDL UEL catted (Emissions and headache witching to stock) headers.
Overpipe
Stage 2 Tune OFT
Double resonated FP
Q300 Catback.
Honestly I'm mostly curious to see what people look for to maximize their N/A set ups. This is for educational purposes more than anything.

my answer: decat the stock header and fp, then dynotune
talk to efi logics in conn, theyre probably not far from you, they installed and dyno tuned the jrsc on my brz. instead of coming up with some weird idea of what youre going to do to make more power, talk to people who do this for a living. trust me, they do this for a living, they know more than us.
as others have said, header and tune are what you do, if e85 is out of the question thats ok, 93 is easier.
all the gains from a header come from the fact that ur changing to a catless one, so the fact that ur considering upgrading headers but staying catless is pointless. i dont care what product descriptions say. also, use oem filters, that goes for engine oil, engine air, cabin air.
what i, and a lot of other people have done is decat the stock header and front pipe. it costs the price of new gaskets. decatted stock system is not loud, sounds great, no rasp. this way you get the hp of catless, keep the sound down, and its hella affordable. dynotune it after you do that. dynotuning is always a great idea. on a bone stock car off the dealer lot, a dynotune could probably yield 10hp, and improve driving feel. remember, driving feel is always more important than 10 hp at redline
so ur looking at ~$65 in gaskets, and ~$600 for a dynotune.
also, placebo pills are great. lower the car a little with stiffer springs (rce yellows etc) and make the car a little louder and its going to feel 100% faster. way better than 10hp at redline will make the car feel.
