You need to replace it or gut it. Those are the only two options. And you do not need to replace it with a MB unit, you can cut the old one out and put the new universal one in its place. Just make sure the new one is at least the same size and a three-way cat. Of course an exhaust shop should do this for you, and don't let them jack you because it is an MB. They like to think that these cars are somehow diferent than any other car out there. When in reality the engine and exhaust is just like any other engine and exhaust as far as operation of it goes.
