Depending on the application there are free flow catalytic converters available. They are not street legal in all states (California for one).
That would depend on the type of vehicle. If it is a low emissions vehicle you have to go with the oem catalytic converter.
Check engine light, low power, poor fuel economy, highly illegal to run without the catalytic converter.Check engine light, low power, poor fuel economy, highly illegal to run without the catalytic converter.
Code PO420 is catalytic converter efficiency low bank 1
This light is indicating a emissions problem or failure. The catalytic converter may be operating at low efficiency which is a sign of failure.
A couple of things could be wrong. number one you could have a check engine light on saying low deficiency out of parameter's. this means that the catalytic converter does not meet the right heat range. If it is to high this could mean that your catalytic converter is plugged. you Will have no power, very sluggish. If it is low you could have no back pressure, the inside of the catalytic converter is empty, this is to cold. it will cause the check engine light to illuminate. This an open loop condition. your computer goes to base settings and you will get very bad fuel economy. To high and to low will cause the check engine light to come on. you will need to replace the catalytic converter.
Low catalytic converter efficiency.
im assuming you mean catalyst efficiency low, and it means that your catalytic converter is not working as well as it should.
a low whistling noise every time you release the gas pedal usually coincides with a dieing catalytic converter Rattle, check engine light, stalling problems, low power, strange exhaust odor,
Check for exhaust leaks, test oxygen sensor operation, replace the catalytic converter.Check for exhaust leaks, test oxygen sensor operation, replace the catalytic converter.
if we are talking about clogged catalytic converter; 1. Lost of power 2. Engine warm up fast 3. press gas pedal, but engine runs low RPM it depends on the % clogged
Yes, it sure can.
