Catalytic converter bypass valve

The reduced workload means the engine will produce the same amount of energy with lesser fuel consumption and better gas mileage. The U. The Environmental Protection Agency has set national guidelines that regulate the removal, replacement, and installation of the catalytic converter. In states like South Dakota and Florida do not have emissions testing.

These toxic fumes can also harm you and your car passengers if the fumes get into your car cabin with the windows closed. If your car has the check engine light on, it will light up on the dashboard display. Though you can fix the check engine light indicator by installing a spacer on your lambda oxygen sensor, you risk the light not working properly again, and it will not detect other issues using this indicator light. Though some car drivers love the healthy noise on an exhaust system without a catalytic converter, the noise can be harmful.

When you drive with your windows down and a full engine, you might receive an exhaust noise of up to decibels.

It exceeds the recommended sound level of 85 decibels which is potentially dangerous to hearing health. If the noise is not disturbing, it will still be loud enough to interfere with conversations. Not all vehicles behave the same way after a catalytic converter removal. Some car owners report increased fuel consumption and reduced low-end torque. The reason for this is that the oxygen sensors stop sending correct readings causing more fuel usage.

To avoid any legal penalties, it is best to replace your damaged catalytic converter instead of bypassing it. We recommend replacing your catalytic converter with the same model and brand as the original one. You can also use aftermarket cats as long as they are EPA certified for your vehicle. There are several ways to find out if you have a bad catalytic converter. The most obvious way is that the check engine light will flash to indicate a problem with the device.

Other symptoms brought about by a bad converter include:. When you scan the check engine light with a code reader and receive the P or P codes, the most likely problem is a faulty catalytic converter. Bounder: 3 Way Diverter Valve Question.

Thread Tools. Looks like maybe a water heater bypass. Posting Rules. Similar Threads. Parts for shower diverter valve. Since my Prius has k miles on it it started burning oil. And lots of it. So the engine light came on, I ran diagnostics and the error comes back to the catalytic converter. So now I have a dilemma. If I replace it it's going to get ruined in a month since the engine is eating oil..

I don't want to be replacing it every now and then since it's a rather expensive part. Is there a way to bypass the sensor, so it would not cause the engine light to come on? I don't want to have a serious trouble and not know about it. The car is in Florida, so there's no inspections that I would have to pass, if that helps anything about this case..

Thank you all for replies! JC Senior Member. ChapmanF Senior Member. I'm not sure what it's called but there is a product that will create space between the cat and the sensor.

You unscrew the sensor, screw in this thing and then screw the sensor into it. I think it's called a non-fouler, not sure. Any NON-reputable exhaust shop should know!
