As I mentioned in your thread mate Akrapovic is 64mm and the upgraded meg exhausts are 3'' (74mm) so maybe this can be a bit restrictive for any future plans? I'm sure you paid good money for the Akrapovic (which is the best exhaust for the 197/200) so I'm only saying that you could have bought what's best for the megane engine, and this is not the Akrapovic.
Mike is running a supercharger so he didn't have to do any mods to his exhaust. He was running an Akrapovic before he supercharged it.
