Good afternoon
This has been a long project!
So I’m building a cafe racer style gt550 and time has come to sort exhausts for it, I’ve managed to find someone that will actually make a set of expansion chambers for me but he needs sizes of the cone to go from, he said he can take the head off and measure the ports and go from that but it doesn’t usually work first time and you end up having to make 2 or 3 sets to make the correct power!
Has anyone made a set? Or have the dimensions to start?
Any help is greatly appreciated!

Think of how stupid the average person is, then realise that half of them are more stupid than that.
