Why mess with the sensor when you can just move it a tad out of the exhaust flow by adding a fouler. If you want to move it back to original spot in the future you can.

I'm jus sayin that it could work and if you hav to get your car inspected every so often they could fail you for tampering with your cat, but I havnt tried it n wouldn't encourage anybody to try it unless you got an extra o2 sensor tht you can mess with because I don't think anybody has tried it before so I was jus putting out an idea.
