I'd run cats from a 2013-2014 GT500.

You can datalog cat temp, I just don't know which o2 sensor it comes from. I've always been catless so I've never needed to do so. As you lean it out the exhaust gases get hotter. Boost generates more exhaust gases.

Can't run a cat that was made to withstand one temperature and pressure, then use it in an application that exceeds the conditions it was ever designed for.
