Depends on where the noise is coming from. It could be a donut gasket after the Y-pipe.

Are you sure it isn't the Fuel Pump? If it sounds like a high pitch whine, it's may very well be the fuel pump on it's way out.

does it vary in sound depending on how much gas you have in the car? anything less than 1/3 of a tank has the fuel pump partially exposed so there will be more noise than usual.
