help me fix theses noises

[DCjuggalo]

well i got a couple of noises coming from my 90k mile 00 gt

-creaking when i back out of my driveway (sounds like something in the rear)

-exhaust leak sound but everything is tight. could it be where the header gaskets? its not a very loud tick but when i get beside a wall i can hear it pretty well

-around 1800-2200 rpm's if im light on the gas, it makes a rattle sound. i thought it was the metal peice that between the block and the tranny but its not. i have a O/R xpipe so its not cats

I have something rattling in my trunk too and it's driving me nuts. Seafoam it to find the exhaust leak

Steering rack bushings?

Just let an exhaust shop sort that one out...

Could this also be the above mentioned exhaust leak?

Since you said you thought the rattle noise was a metal peice is it more like a ringing or a rattle.

There is a little metal tab in the back of your seat that is not welded very well. When it gets loose it squeaks and makes noise. You just bend it up with a screwdriver. I'll look for some old pics I had.

Might not be that, but if it is, it's an easy fix.
Good luck.
