How much louder is the FI with 18" resonators compared to the stock NISMO exhaust?

I have the FI w/ 12" resonators and FI LTH on my 09 nismo and it is night and day from stock. Like a different car almost...HR engine on steroids. The volume is not headache-inducing nor is the exhaust note super different from stock, just really enhances the growl like the pipes are up to a megaphone. There is the typical hiss/buzz at cruising and lower rpm and a lot of cabin drone. But imPo there is no better full exhaust. If you're on the fence I say definitely go for FI!!!! Full disclosure, I didn't personally install it but the previous owner did (and babied her - thank you ryanboy) which is why I bought her. I'm in love and from what I can tell all other FI customers are very happy as well.
