To Cat or not to Cat
FYI From MercedesShop.com Parts Department:
We have fantastic prices on aftermarket Cat/Converters. The 48 state as well as California, with a fantastic warranty. Five years or 50,000 miles. Give me a call if you have a need.
In most states, I belive all, not sure, there is a hefty fine that goes with removing your Catalytic Converters.
