I have resonated HFC's (FI). The hiss is barely audible. I really have to slow down, cut the radio off, put the windows down, then accelerate in a low gear and lift off the throttle, and I can just make out the hiss. The resonators in a set of upgraded HFC's will mute about 90% of the hissing noise. As you open up the HFC's further (non-resonated, lower Count - I have the 300 count HFC's, but you can specify 100 count - better breathing), the louder the hiss. And then there are the test pipes that are pretty much wide open for noise. I have not heard a 370 with test pipes yet, but I can imagine it would be King Cobra hissing on Steroids...
