Well i have had the nismo and its not really a loud exhaust at all.
I am sure you could gt a much better and deeper sound from the fast intentions.
About gains, the gains are going to be very minimal since you already have the nismo paired with berk hfc's.
If you do buy another exhaust, it will most likely be to change the sound.
As far as i know, fast intentions has the most gains so if ur going to get another exhaust it better damn be a fi.
