Got the baffle out, going to remove all pipes inside the cans

It's the weight of the original cans that can see the problem, you could try removing the brackets to see if it fixes the problem.
I'm not sure if that would help, as they are both rubber mounted at the footrest mounting points with the OEM standard footrests and at the pillion footrest hangers, rubber mounted there too.
