First upgrade?
 

What do you recommend for the first upgrade? Something thats not to expensive but gives me a good amount of HP.

high flow cats for sure. followed by a CBE, followed by intakes.

K&N drop-ins - cheap, about 5HP - but not if you plan on CAI
Berk HFC - pain to install, also see recent (lack of) heat shield thread, good gains
CBE or Tanabe Y-tube
new Manifold or something expensive :)

CAI for starters, then exhaust system.

Congrats and Welcome! :hello:

Normally the cheapest mod is to go with aftermarket HFC's, then a CAI followed by a CBE followed then by a Tune?

go all out bro Full Titanium Exhaust Amuse had one of these in my S and loved it 8 pounds =)
oh yeah Intakes are always a good start
