You dont have to cut the hood. Im running a 4g63t without the hump hood. Id recommend running a hump hood though. There are two styles of CF hoods for the 7g. One with the Hump and one without(Vis). I bought the Vis cf hood thinking it had hte hump, sadly it did not.

DjPlay originally started the first gb for the humped cf hoods. Not sure where you can get them nowadays. But the widely available VIS cf hoods do not have humps(unless they changed them withint the last year and a half)
