Message	On my first Z i had the same kind of issue, and i could find it either. Finally when i pulled my motor for a full rebuild and went with MS manis i found that my stock pass manifold had cracked and must have been the cause for the sound i experienced. Yours might not be this exactly, but definately sounds like exhaust leak of some kind.
