Well my upstream o2 sensor burnt out, So should I buy a denso for 288$ from autozone and get lifetime warranty or should I buy an OEM online for 315$? Are denso any good or is it gone a burn up all the time becusae I'm catless?

I plan on just removing the back o2 sensor in the spring. You can turn it off with the Cobb software. Doesn't do jack anyways with a test pipe.
