You cut it off of the exhaust system and replace it with a straight piece of exhaust pipe Know that it is illegal to remove a converter without replacing it with a new one.
It is illegal to remove a catalytic converter without replacing it. Don't cut it off, unbolt it.
Yes. Just as a raw potato plugging up a exhaust pipe can cause a car not to start.
it is in line in your exhaust system, not an easy repair, need to put vehicle on lift, cut off old one, install new..
You don't have to change or remove the converter unless the converter is stopped up.
take off the electrical monitoring system, then just cut it off. as long as you live in a small town without emission standards on inspection, you should be good. Or you could cut the exhaust right after the cat and shove a small pole in it to break up the beads. The exhaust should push them all out after a day or two, giving you better exhaust flow.
First off, O2 sensors are not located on the motor! There are 4 - O2 sensors for the freestars. They are located on the exhaust piping, 1 off each exhaust manifold (2 exhaust manifolds in a V 6) before the Catholic converter and 1 off each exhaust tubing further down after the catholic converter ( 2 exhaust tubing).
It sound like your catalic convertor is stopped up. Unbolt it and drive it. If it runs a lot better, replace it or leave it off.
Oxygen sensors are pre catalytic converter and post catalytic converter. This means they are somewhere in the exhaust system. Sometimes in the exhaust manifolds or exhaust pipe right off of the engine for the pre cat and in the exhaust pipe immediately after the converter for the post type. Some vehicles have up to 4, yours has 4.
Catalytic converters are located up towards the front of the exhaust system - typically right after the pipe comes down off the engine's exhaust manifolds. If the vehicle has a single exhaust system, there will be a "Y-pipe" bringing the two exhaust manifold pipes together - the catalytic converter will be just past this. If the car has dual exhaust, there will be a catalytic converter for each.
Should you cut off the catalytic converter? No. But can you and will SOME vehicles actually benefit? Yes. It is illegal to remove any emmision control device from your vehicle in most if not all states. For countries such as Mexico where it is not illegal, some vehicles without downstream Oxygen sensors (after the catalytic converter) it can have some benefits. It is really the same benefit as a free flowing exhaust. Modern (97+) cars already have a free flowing design catalytic converter so there is no benefit to doing this.
It is connected to the pipe off the exhaust manifold in the bottom outside of the car.
