Any Vehicle In most parts of Canada and Usa does not need to have a Catalytic Converter If it was made Jan 1,1995 and earlier.It will flow better and probably get more powerand mileage
When it was built, It had one.
Yes it had 1 from the factory.
Catalytic Converter is clogged.
Brown and Brown in Mesa Arizona is charging me $1300.00 to replace the catalytic converter and fuel filter.
Upstream would be before the catalytic converter. Downstream would be after the catalytic converter.
There are multiple O2 sensors on a 2002 Chevy truck. They are all located on the exhaust system. There will be pre catalytic converter and post catalytic converter sensors.
Depending on where you live, you MAY be in violation of emissions law.
Yes, and it is also illegal to remove the catalytic converter. Your engine will not run properly with the converter removed and will have less power and will use more fuel.
Yes, That year MUST have 1 are it will not run right. No way around it.
It sure did, That is the law on all makes and models.
I have a 1987 Chevy Silverado 350 tbi that runs just fine without the catalytic converter. I run dual exhaust from each side of the engine with glass packs, has more power and sounds great.......SES light comes on but will go off.......
It doesn't need one to run, but it probably won,t pass emission tests
