I'm looking for hte part number of the donut gasket that goes between the exhaust header and catalytic converter. I can't find anything.

 

Was there a gasket between the exhaust manifold outlet flange and the catalytic converter when your removed it?


If memory serves, I don't recall seeing one as the flange for the converter fits inside the exhaust manifold.

 

I haven't removed it yet, but there's a minor exhaust leak coming from there, so I assumed it had one, and is bad.

 

Check to see if the nuts on the flange are tight first before removing anything.

 

It's a ball flange fit. The nuts shoulder up onto the studs and will break off if you over torque them. Most likely the flange has bent allowing the ball socket fit to loosen from exhaust or engine movement. Make sure your engine mounts are good by trying to move the car forward and back with the brakes locked and the hood open. You'll see the engine lift if the mounts are bad. Per the leak, get the flanges straightened or replaced.
