You need to take a video of the sound so we can get a better idea of what it is. Right now, it's difficult to tell what it may be.

First and foremost, lol "foremost" I got few problems with the FR-S. The steering wheel is now stiffer than usual. I changed the fluid but still stiff.

Moving on, when and only when the AC is on. I hear I grinding noise when I am driving and then shift to neutral. As I am braking the noise will come

There is no specific RPM range where the noise come, but it comes infrequently. Maybe it comes while I am driving. I don't hear it though, full exhaust changed.

And also, I presume you used power steering fluid when you changed the fluid. If so, you need to figure out what fluid you did change (probably clutch or brake) and flush the affected system. Or things may break.
