Gen 2 Catalytic Converter Stolen - Don’t Know What to Do

I just went through this. The new one needs to be welded on. Take it to a muffler shop and they will do it. Also ask them to put a shield on to prevent it from happening again.

Furthermore, you may need a new O2 sensor if they clipped that, and also the inner gasket 'donut' which aftermarket units are prone to leak, ours was kind of cracked so I decided to buy a new OEM unit in order to get a proper seal on our aftermarket unit. Hopefully this car is good for another 50k+ as the guys in the shop stated.

You can do it yourself if you're motivated enough, but you'll need to weld the unit to the resonator (assuming that's intact) to ensure a proper seal and avoid leaks and aligning it while on the ground isn't impossible but worth having someone do it if you don't have a lift. The little clamps that come with aftermarket units are worthless and will leak after a few miles.
