I have them and the hiss used to be really noticeable but after 2-3 weeks it subsided a lot. Now after years of having them i can't even hear the hiss anymore. I personally found it very annoying. It sounded like an air leak.

Once the pipes are internally coated with carbon it will muffle the sound, so there's no cause for concern.

I would say the hiss from my flex pipes would be marginally louder than the toda.
4 flex pipes vs 1 or 2 flex pipes on the toda...
