It is illegal to bypass the catalytic converter and besides your engine will not run correctly if you bypass or remove the converter.
No. It's illegal.
No!
You can remove it and put a pipe there, or you can remove the exhaust pipe and drive a piece of pipe through it if it's clogged up, but beware of the EPA laws. The check engine light will stay on if you remove the converter and the vehicle will not run correctly. It is illegal to remove a catalytic converter.
You don't not legally anyway. You could put in a straight through exhaust line, but if you're caught you could be severely fined.
You can't.
Modern cars use two oxygen sensors to monitor the exhaust before and after the catalytic converter. Removing the catalytic converter would cause your engine to run improperly, possibly causing damage and most likely making your gas mileage worse. Just replace it if it's broken.
No, this is illegal and carries a hefty fine if you are caught. Besides your car will not run properly if you bypass the converter.
Sure but the second you go for emissions testing you will be screwed because the exhaust will be contaminated.In a way no you cant and don't try because there are very bad fines for driving a car like that.
You can't.
fords use this. maybe others but only ford calls it a dpfe. [differential pressure feedback e.g.r] they were notorious failures in the 90's . what the do is bypass a little exhaust through an oriface tube on either side of the catalytic converter. the dpfe measures the pressure difference to determine if the cat is plugged [ or not doing its job] if it measures values out of range it will set a trouble code.
