I wonder if you have any audio clips with them installed. Stock and CBE version exhaust too.

I like the idea of reduced obstruction/greater flow but with some noise reduction too. I would like to add these into a CBE exhaust but not at the expense of noise.

"Noise" is personally subjective. If the restriction (OEM catalytic converters) is removed lower frequency noise will be generated. The resonated sections help reduce noise in some of the frequency bands but lower frequency sound will still be heard.
