When people post "but its only 5hp", you're missing the point.
Modifications are synergistic. They all work together. Sure JUST HFC's might yield 5whp (just guessing) but when you add other components, they all work together to make the most power.
Any one particular part might not be a great bang for the buck, but when you start adding them together, thats where you get the benefits.
I can guarantee that adding HFC's to an already existing free flowing 3" cat-back exhaust system is going to yield noticeably more power than doing "just HFCs".
