Catalytic converter making a rattling noise when accelerating is indicitive of?
 

As the title states... Unfortunately, I don't know much more about the issue as this was all the information I was provided about the vehicle in question.

I'd like to have some idea of what might be causing this; what questions I should ask in order to have a more definitive idea of what the problem might be and/or what the possible repair costs for something along these lines might entail.

This is a vehicle I'm considering purchasing as seems to be about the only blemish on it.

It has 114,000 miles, the transmission was rebuilt at 80,000. The interior is in prime condition and the seller has a complete history of all maintenence.

As always.. All help/assistance/advice is appreciated.

Catalytic converter making a rattling noise when accelerating is indicitive of........ a loose heat shield. just jack up the car and tighten up the bolt or take off the shield alltogether. common proble/noise in the svx.

It might just be your heat shields and not the catalytic converter

Jack up your car and check to see if it is just the heat shields that are rattling. Once you get under there you will see what the heat sheilds are. They run the entire length of the echaust system. Just grab ahold of them and shake 'em tillyou see which is making the noise

In my case it was something loose inside the resonator. I had it chopped out and replaced with a glasspack, and the rattle went away. :)
