Intake: Stillen, Injen, or AEM Cold Air Intake
Exhuast: Stillen, F.I., HKS
Headers: HR Longtubes
Tune: UpRev Tune, Cobb AP

So, I've calculated the costs of each part and compared it with the amount of hp increase.

~$500 for a tune for ~10 hp and 8tq
~$1700 - $2500 for catback for ~10-20 hp
~$1300 for headers for ~10-20 hp
~$500 - $800 for an intake for ~5hp-10 hp

When you think about the cost vs the hp gain, it just doesn't seem worth it. Or am I the only one that feels this way?
