How to remove Akrapovic baffle from 2011 RR..?

Hi, I've just got this bike and it has a akrapovic exhaust like shown in the below link.

How do you get the baffle out as the bolt holding it is opposite the swing arm.. So trying to fit a rachet inbetween the exhaust and swingarm is impossible..

Take the can off if you don’t have a tool to access it in-situ? It’s only a bolt and two springs.

 

I tried taking it off but it wont slip off... I think i'll have to leave it in

 

I always take the end can off when I want to remove the baffle.
