If the catalytic converter was stolen, why would you not have your insurance or the shop that stole it, properly replace the thing?

Maybe you could elaborate on what happened, how does one steal a catalytic converter?

why do you even what to steal a old catalytic converte? It's like breaking into the bank valuet and steal the floor carpet or something.

Dont think that it's wise to remove the catalytic converte, the car needs alittle back pressure I think. Have you removed the resonator or changed into a aftermarket muffler? If so, the noise will also be much higher.

I was wondering that myself and then I read this on Wikipedia.

Theft

Due to the external location and the use of valuable precious metals including platinum, palladium, and rhodium, converters are a target for thieves. The problem is especially common among late-model Toyota trucks and SUVs, due to their high ground clearance and easily-removed bolt-on catalytic converters. Welded-in converters are also at risk of theft from SUVs and trucks, as they can be easily removed with a battery powered reciprocating saw.[8][9] The saw removal of the converter can often inadvertently damage the car’s wiring or fuel line resulting in dangerous consequences. Rises in metal costs inside the United States during recent years have led to a large increase in theft incidents of the converter.

Mercedes and BMWs are supposed to have cats with higher amounts of recoverable precious metals in them, so that is why they are also popular. The unscrupulous recyclers will pay more for them. More methamphetamine fixes for your effort ;) My local indie wants you to either get you car to his place before 5 pm so he can store it overnight in his shop or don't drop it off until they open the next day.

I would not let the body shop "weld" something on my car to avoid replacing something that was intended to be there, like the flanges that hold the cat on in the first place. It is only my oppinion that there is more to this story than keyslk230 is letting on, but if its all the same YES there is going to be problems whenever a sensor or system has been altered, damaged or removed. Especially considering mercedes highley engineered and time tested engine management system.
