Is it common on the GTR to have exhaust hiss upon deceleration similar to that of the VQ 370z platform? My GTC Titan Super Street is exhibiting this at about 3k rpm upon decel. I've never really heard anyone else talk about it on here.

Anyone? I'll try and take a video for people not familiar with this sound.

No, it's not an exhaust leak this is distinctly different. 

 

This video is actually a perfect example of what I'm talking about. Listen to the sound it makes as the rpm's come back down after a rev. Like I said, it's very common on the VQ platform but I've never heard a GTR owner talk about it before.
