HFC Owners
I am in a massive internal debate with myself over getting HFCs. I want the extra power but am concerned about a few things.
1) Too loud over all (db)
2) Massive "drone" while cruising at highway speeds
3) CES issues
4) Cost
5) Sounding to "raspy"
So, someone that has them, please educate me and help me out so I can make up my mind.
Thanks in advance

I have Stillen HFC's with a Stillen exhaust. When accelerating hard, the noise is louder then when I just had my Stillen exhaust. The noise is more raspy. But, at cruising speeds on the freeway, there is not much difference. Also, when I don't want to make noise, I can lightly accelerate. I am really happy with the HFC. It's great bolt on power for your buck.

They all look to be very similar if not the same, well that goes for the Berk and FI HFCs. The Berk is the only one that has a independent dyno with it which was done by me. No one else dynoed their car before and after their HFC install and posted it on here so we really don't know if there is a performance difference between them.

I frankly don't like how my HFCs made my stock exhaust sound at startup and at WOT. It's louder now, but sounds kinda raspy/tinny. Looking for an aftermarket exhaust with a deeper, but not too loud note.
