Any tips on this, it seems to be getting worse.

My exhaust sounds awesome but the rasp on overrun is starting to get to me. It wil start at about 4k revs. It now even rasps when I change gears (calmly).

The sound seems to be coming from the slipons, almost like something is loose or tattered, giving this rasp or almost a fart sound when I am not giving petrol. Could it be that the cans needs to be repacked? Its akropovic slipons, I do not know much when it comes to exhaust science. Should I just start to strip and see what I find or will I be looking in the wrong place?
