Hey I got the clicking to stop here is what i did. took off the heat shield and located a crack in the exhaust manifold. then I used a product QuickSteel for high temperature can pick it up at any auto parts store I then mixed it up till it looked like toothpaste. then I let it stand for about four and a half hours before testing I went around the block and the noise was gone. I would let it stand for 24 hours though if I were you before you test it when I tested mine it made a giant bubble. Fortunately it held and I just pushed it back in place.I'm not sure how long it will hold up but for 10 busks and 10 minutes of work time its worth a shot verse 150 bucks and between 1-3 hours of work time. At least we know what the sound is and can fix it now.

Can anyone confirm that they have the same noise that is in Z06killers video ? also found at this link

 

It is exactly what I have. Almost sounds driveline related, possible axle or front drive shaft being that it is AWD. It does NOT make the sound during rev only under driving acceleration.

 

 

 

I do hate the sound but more interested in making sure it isnt something major that can go out on me while driving.

Yes, I have the exact same problem and noise that just started last week.

Does it sound like gravel hitting a piece of tin? No rhythm to it but increases with acceleration? It could be a piece of loose honeycomb in the catalytic

Starter kick out spring is weak or washer that holds the kick out fork is coming loose/off the grove inside the starter, let's it touch the flywheel at times. Also from what others have said possibly crack in the manifold..
