My akrapovic is etched on the outlet end with part number.
Also not all akras have springs to the link pipe, on my gen2 the pipe and can are one piece.
When I had my gen1 I fitted an akra can to a non akra link pipe with a clamp but there were hooks on the can to attach springs to, if your can does not have any hookss then it is probably a fake.
Looking at your link pipe it has hooks on it but it also looks slightly damaged, maybe had an akra fitted that got damaged and a cheaper can was put on.
