The semi-metallic PB pads have a bit of noise and lots of dust, but still nothing to be concerned about. And I would say EBC orange, which are a step up, are surprisingly quiet for a track pad. Going down to the yellow stuff, you can still hear a tiny bit of noise. But it is like a faint 'air'ish kind of noise. Not a squal.and between EBC and PB, are the EBC any quieter ?Definitely not quieter than OEM right ?
