quick question:
if there is an obvious exhaust leak coming from the front side of the car would the chances favor it being the collector, or the header gasket to the head leaking?? I just don't wanna go torkin down header bolts and breaking one. I just can't tell from under the hood if it's the collector or not... Please help!

Get a piece of heater hose, use it as a stethoscope; stick one end in your ear, probe aound with the other end, you should be able to pinpoint the source of the noise.

 

tried it out and it worked! it's the header gasket. rats! i'm payin somebody to play games with those rusty bolts.
