OK to bypass a catalytic converter in Minnesota?


can you legaly bypass a cat[lytic converter in mn


No, if it’s less than 25 years old I think. Why would you? You can get one replaced pretty cheap at a muffler shop.


No. It is not legal to remove a catalyst from a car originally equipped with one. If you have emissions testing you’ll fail.


And if your car has an oxygen sensor you’ll mess up the engine operation.



No but its a federal thing not state.


It can be a state thing too.
