That's the exact noise I'm getting, but I've got Borla, not nismo.

If you rev your motor in neutral you can hear it after the RPM's come back down right?

I have that problem too.I had test pipes installed on my hr and if I get on the gas had it makes that exact same sound.its the loudest at about 2500-3200 rpm when full throttle.is there anything I can do about it its a really loud annoying buzzing hissing sound.
I've taken to a muffler shop and they said the exhaust is perfect no leaks or anything.
