VQ Hiss or other rattle?

Odd.
I have Invidia Gemini V2 and the only hiss I ever experienced is if I'm pushing the car very hard and if the climate control is on, then I hear some hissing when letting off the gas - I suspect it might be due to the A/C compressor spinning on a bit higher rpm's. Otherwise I have no issues with the said exhaust and VQ combo.

Im running AAM resonated test pipes and have a noticeable "hiss" on decel when letting off the throttle it is a short airy noise, not long or extended burst its really not even intrusive tbh and my Z1 14-lb flywheel makes more then enough noise to cover it up once it gets hot

Hmmm my noise seems more metallic than airy but I suppose it could be the same thing. My test pipes are unresonated so that could make it worse in my case.

The sound will also continue to ‘rattle’ for as long as I decelerate or coast <2500 RPM. (Think coasting/engine braking down a hill)

Do you have stock cats still? The hiss that everyone talks about is more prominent when switching to HFCs or TPs
