O2 Sensor Recommendations?

[ViperTony]

I'm installing high-flow cats and 3" exhaust on my '01 RT/10. I know there's a 50/50 chance that the downstream O2 sensors won't work properly and throw a check engine light. Which O2 sensors would you recommend and where can I get them?

Thanks,

Normally the downstream O2 sensors become a problem if you run without cats. Putting in high flow cats should not cause any problems.

Thanks John. Just in case it does cause a problem, do you have any recommendations on O2 sensors?

You will probably have to go with sims as I would think all sensors would be somewhat the same unless aftermarket ones have a more forgiving wider range.

I never had problems on the 98 with RT 3" hi-flows and 3" Corsa.

Most experts have said the stock 02 sensors are the best way to go. If you throw a code for some reason, you should go with 02 sims just like ViperJoe susggested.
