I would have gone with G56 for my new car (as would appear not to be as loud as the MMC stage 1 kit) but decided to go with the latter so as to avoid any possibility of Morgan saying the G56 one would invalidate the factory engine warranty. I believe the supply issues will be sorted shortly but not in time for my build so I will get my dealer to retrofit the MMC kit once one becomes available. Obviously no potential warranty issues if you're fitting the kit to an older car where the factory warranty has already expired.
