Nissan 370Z Forum - View Single Post - HFCS resonated vs non-resonated sound diff

So I currently have FI resonated HFCs. I am thinking of getting momentum headers and z1 350z HFCs which I do not believe are resonated. I was wodnering how the new non-resonated cats will sound different. Will there be more drone or rasp? Will it be any louder?

Any input on how headers will sound will be helpful as well. I don't want my car to be super loud. Where it's at currently in terms of volume is just right, don't want to be much louder.
