Your intake is good (Ford Racing) and the exhaust is good too.
For a Normally Aspirated car the long tubes and such wont really buy ya anything. The Underdrives will grab (reclaim) ya about 5 horses.
Best thing you can do without going Forced induction is to get it tuned on a dyno by good tuner.
Or a mailorder tune from like Brenspeed, or Dynojoe will gain ya too.
Since I dont know where ya live I cant recommend.
Ya can always add NOS if ya dont want to spend the money on FI.
If you go FI then the whole world opens up for gains.
