You want to remove your catalytic converter on a 2000 Chevy S10 Blazer but not set trouble code is there way fool the computer?

Yes, there are a few ways to fool the computer on a 2000 Chevy S10 Blazer when removing the catalytic converter. Here are two common methods:

1. Oxygen Sensor Spacer:

- Install an oxygen sensor spacer between the oxygen sensor and the exhaust pipe. This spacer will provide additional space for the oxygen sensor to move, preventing it from detecting the increased emissions caused by the removal of the catalytic converter.

2. Spark Plug Non-Fouler:

- Use a spark plug non-fouler as an oxygen sensor spacer. A spark plug non-fouler is a small metal tube with threads on one end and a larger opening on the other end. Screw the non-fouler into the oxygen sensor bung, then screw the oxygen sensor into the non-fouler. The non-fouler will provide enough space for the oxygen sensor to move, fooling the computer.

Additional Notes:

Keep in mind that these methods may not be legal or compliant with emission regulations in all areas. Removing the catalytic converter can result in increased pollution, so it's important to check local laws and regulations before modifying your exhaust system.
