To put this thread to bed - finally managed to get a response from the mysterious AutoPrestige out of Japan.
I was asking for availability/price for the 961 carbon single seat unit and carbon airbox mainly - plus high level exhaust (mostly out of curiosity). The quality looked excellent.
Waaaaay too slow, they have clearly moved on to other things; worth a try. It appears though, Stu is even famous in the ‘land of the rising sun’

I asked them 4 years ago the same answer, for the exhaust only.
This is what I got back, I decided also to leave it as is.

Thank you for contacting us.
Our original exhaust: 102dB/3500rpm
(For your reference)
Dominator normal exhaust: 94dB/3500rpm
Cafe Racer normal exhaust: 92dB/3500rpm
Measured by the Japanese standard which is 45 dgrees and 50 cm behind the exhaust tip. Please see attached picture.
We are able to make it less loud if you like.
You might need to adjust the stay since there will be a individual difference.
If you want us to make a quote, please send us more details of your vehicle such as model year, what 961 you have and so on.
Should you have any further questions, feel free to let us know.
