Maybe there's a snake under your seat?

It's the nature of the VQs motor making its hiss. This topic is covered all over.
The real question is. You think Randy Rodriguez knew about the hiss when he designed the front fascia on the Z?

LOL... I Love my Fangs even more now!

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...

Don't know what TP's hiss like but I can tell you from experience that LTH's with a non-res CBE, hiss louder than any snake I've ever heard.
