HFC Owners
Fast Intentions. I actually bought some Stillen's, but never installed them because I didn't like how they looked (not polished, had that "not for use on the highway" stamp on it, etc.). I'll probably put those on sale soon. I went with FI's because of the cleaner-looking welds, the fact that it was all polished, etc. Performance-wise, they're most likely the same, since when I looked at them side by side, I noticed that the actual cat was the same design and is probably sourced from the same manufacturer, Carsound/Magnaflow.
No drone from the HFCs on this car.
There is a difference at highway speeds however between 75 and 80 MPH the exhaust is a little louder under slight load. It's not a "drone" just a more audible tone. It's not terribly intrusive but you will hear the exhaust hummm a little more at 3K RPM. Many people wil like that sound however.
