Its funny that this came back up while I'm on my lunch break.
So my rattle issue continues but I found a major culprit. It appears the previous owner of my Z somehow bent down the heat shielding that is right at the Y pipe. it was bent down and touching the top of the Y pipe. It was actually worn through in some places where the constant vibrations had beaten away at the metal.
After discovering this, I bent the metal shielding back upwards to its original position and went for a drive. THE SOUND WAS GONE....for about 2 gears worth of a pull and then the metal bent back down onto the Y pipe.
This explains the hot cold issues where the rattle is worse in the winter because the metal contracts and ends up bent back down where the "memory" from being bent there for so long is stronger than the "original" location.
I have looked on the parts fische in every section that I can think of and cannot find a place to order that specific piece of heat shielding. This has kinda been on hold as I have been working in Missouri for 6 months and seem to be always busy. Will visit the dealer back home when I'm finished here because the one here was even less friendly (which I didnt think was possible) "Oh yeah we don't normally work on modified cars"...
Anyways in the time of silence between that metal rattling I have heard other little rattles developing, I am almost at 70,000 miles so I guess it is just a factor of time that stuff will start coming loose. @dmarando I haven't checked this area and I will definitely take a look there!
