Know that it is illegal to remove the converters. Also know that the engine will not perform correctly with the converters removed.
No, it's illegal to remove the converter. Besides the engine will not run correctly with the converter removed.
The catalytic converters "burn" unused hydrocarbons, including raw and partially burned gasoline, and CAN burn small amounts of engine oil, providing that the engine isn't TOO messed up. But engine oil often has additives that can eventually destroy the catalytic converter. co and no is removed via Catalytic Converter
I would not touch it except to install a converter.
If the car is buit after 1996 you will need to install a new catalytic converter to get check engine light to go out if the code is for the cat.
I doubt it would even run and if it does I hope you have a lot of credit on your gas card. :-)
They will still work with no converters. The O2 sensor downstream from the catalytic converter is there to monitor the function of the converter its self. So if you remove the converter, the second sensor will trigger the "check engine" light. The sensors (and the entire engine its self) is not effected, however. The light is basically just telling you the converter is no longer working, which is no surprise if it has been removed.
First off it is illegal to remove the converter. Secondly, your engine will not run properly with the converter removed.---That's not entirely correct. It depends on whether your car is pre-1975, or ALDL, OBDI or OBDII equipped.Prior to about 1975, there were no converters on cars, generally speaking.ALDL and OBDI cars have oxygen (O2) sensors before the converters, and only measure emissions coming out of the exhaust manifolds.OBDII came on line in 1996 (Generally speaking. Some 1994 and later GM models have a modified OBDII.), so if your car was manufactured BEFORE 1996, your car CAN operate properly without catalytic converters. But it shouldn't.OBDII cars cannot (without digging into the electrical system of the engine) operate properly without catalytic converters. OBDII cars have O2 sensors both before and after the converters, and the computer compares the numbers. This is why you have to have the converters on OBDII cars.But, as has been stated, if your car came with a converter, you have to keep a converter on the car.You can buy aftermarket performance converters that will allow you to pass emissions, keep your car legal and are less restrictive than a stock converter, but the performance gains are negligible (1 or 2 hp on average) and the costs are prohibitive.If your converters are functioning properly, keep them where they are. If the converters are clogged or have melted, you'll need to find out WHY and then replace them.
They are not removed. They are converted from CO and NOx to CO2 and N2.
convertersAnother contributor wrote in that he removed 2 of the 4 converters ( repositioned the O2 sensors ) and finally got the 22mpg as advertised by Ford ( previously only 17mpg )without causing any engine codes. It seems logical that without the added restriction that more power and torque would be available. Messing with the emissions system is illegal and I would definitely recommend replacing the muffler.
If you're referring to removing the catalytic converter from your vehicle, first off this is illegal. Secondly no modern engine will run properly with the catalytic converter removed. You must have a fully functional catalytic converter in place.
One who removed things that were previously installed.
