Had a reply from Mivv this morning and it is the wrong can. I think the link pipe is correct though. Weird?!
Well, mine's on. And its f@cking loud with the baffle out. I have a feeling that the baffle will have to go back in.
I live between my inlaws and my son's teacher, and will be using the bike for commuting, so leaving at 7am or so. I think I would be very unpopular with 3 key families leaving the baffle out.
