I have the studs from my headers/cats sitting in the garage, if you need them for the time being let me know and I'll send them down (I'm up in CT but get down to the City pretty often).

+1 There is really no way that a test pipes could cause the issues you are stating, as I said via PM I would double check the installation I am sure something is wrong, especially considering you broke one of the bolts, that could be your problem.

Let me know if you need any help.

Could you be mistaking rattle with rasp?

He's referring the VQ's typical sound that you can find from any G/Zs.

Any Z or G have this sound..even mine is a stock exhaust. I still can hear them.

i know some people who isntalled test pipes the mechanic would push the y-pipe a little too much and rip that to cause a rattle. put the stock cats in and see if you hair some rattle or air loss too
