You can cut an access panel in it, empty it out and weld it closed.

Whatever you do, don’t keep driving it. Unless you wanna blow the bolt heads off the headers

Pull it, hammer a piece of rebar through it. Knock all the shit out of it. Reinstall.

If you pull it off and soak it in the can of berryman carb cleaner. To soak it, you may need 2 or 3 cans(gallons).

Then blow it out with air after a day of soaking.

Flood cat with high flash point solvent, let sit for 24 hrs.. drain, reinstall, and go on spirited drive with lots of Italian tuneup.

Take it out on a back road, put the pedal to the floor a few times until you see a big black puff of smoke come out the tailpipe. I have done it on many vehicles. Just did it on my Tahoe a couple weeks ago.
