2 1/2" or 3"

Don't mean to be smart but good luck keeping 715 hp. quiet.
Hay mike thets not beening smart.This is why I put this out there.So far I dont see anything out there to quiet this thing down.I havent seen mufflers with 3" that say quiet thats why I was thinking of 2 1/2"s.I know I am going to have to use 3" exhaust I am just tring to talk my self out of it.
