Compliance with environmental standards requires any modern vehicle to have a catalytic converter installed in front of the exhaust pipe, and it breaks down over time, just like any auto part. Honda catalytic converter scrap prices are set by a specialized company that purchases car parts.

Due to the catalytic converter wear, the vehicle begins to "choke" with its own exhaust gases. It is necessary to replace the converter to avoid possible problems with the engine. A new spare part has a high cost since it contains platinum, palladium, and other precious metals. For this reason, some vehicle users decide to remove the catalyst.

It is impossible to remove or cut out the converter without consequences. The car electronics system is programmed to eliminate the risk of harmful emissions to occur. Special oxygen sensors are installed in front of or after the mechanism itself to control this process. This oxygen device can measure the amount of environmental contaminants in the exhaust before and after passing through the catalyst. If the showings coincide, the exhaust is not purified, and the vehicle starts operation in an emergency mode. An error signal appears on the dashboard, engine power is artificially reduced.

Having removed the converter, vehicle users replace it with a flame arrester or stronger to ensure that their vehicles operate normally.

Here are the types of simulators to consider:

● mechanical;

● electronic.

The mechanical device has a simple structure. It is necessary to install an adapter that is fitted with a filter to purify the air. The adapter enables the sensor to trace the air purification.

The electronic simulator features a capacitor and a resistor. They weaken the power of the device’s signal. In turn, the car's computer records the absence of harmful impurities in the exhaust at the output.

Re-flashing ECU

Upon the converter’s removal, interested parties can remove the second sensor from the algorithm through re-flashing. This procedure is simple but should be carried out by specialists, since there is a possibility of incorrect programming and resetting other settings required for the vehicle.

Here is an overview of the re-flashing process:

● the computer is plugged in for the vehicle diagnostics;

● a new version of the engine control software is installed;

● tests are carried out to ensure there are no errors.
