Well, the heat shield is off now so it has to stay like that.
I just thought l would see if it could be done easily and it’s not really that hard.
The bracket on the clamp was easy to cut off, the one on the pipe more tricky.
First l sawed it off with a hacksaw and then cut off as much of the remaining weld as possible
After that l filed it down until smooth then painted with high temperature matt black.
It was just an interim thing until l can afford the Akrapovic can but at £500 (an eighth of what l paid for the bike!) it might have to wait until later in the year.
