How much do it cost to get a new cadillac converter for a 2012 BMW 7 series?

It's very expensive. Buying a used car that cost close to or around $100K to purchase when it was new means you're going to pay a lot for any parts. Pats pricing t. I would recommend going to a muffler shop for the best prices. It won't be inexpensive, but it will be cheaper than going to a dealer, and replacing the entire exhaust. 

Go to a muffler shop and ask about a "Jobber" catalytic converter.     A jobber is a manufacturer that just makes "Cats" for all makes of cars.   A beemer one cost like 3 times the price.  They both do the same thing.

Catalytic converter, not a cadillac converter, you hillbilly.

I am sure that most any Cadillac dealer would be happy to give you a quote on what it would cost to convert your BMW to a new one of their vehicles.  

The BMW is way better than a Cadillac, I wouldn’t convert it.

Cadillac is a car brand/name. If you have enough money to own a BMW how about learning some English? It's not how much "do" it cost...it's how much "does" it cost and the name of the converter is a Catalytic converter jojo. How about calling an auto parts store for a quote?

I do know that European cars are much more expensive to maintain and repair. There are far too many variables to give you an accurate answer to your question.

i would call a place that sells them and ask them that
