OK here's where I'm at...got this 00 gt bout 2months ago...dealer didn't list the mods...but so far i've found bbk cai, BB throttle body, PI upper intake manifold I THINK - long tubeheaders, bbk h pipe W/ cats, and I dunno what the exhaust is but its aftermarket.
So when the car warms up and its under load at about 2 to 3k rpm in 3rd 4th or 5th gear it rattles like CRAZY what sounds to be beneath either the passenger floor, or the center of the car.
I got 2 huge hose clamps and torqued those suckers around the passenger cat to rule out a heat shield rattle and that didnt work. When I tap the cat w/ a mallet no rattle at all.
My 2 guesses here are either the passenger cat is clogged (console area gets just a little warm sometimes) OR the clutch cable heat shield that someone described (I don't know what it looks like though)
This rattle is really obnoxious when I pull out of a toll booth or something so its definitely audible from outside the car, and it does do it in neutral but not nearly as loud...in fact u have to be laying on the ground next to it to hear it.
ANY input would be cool! thanks
