Do the pentastar jks have a secondary cat that isn't monitored?

I haven't had a chance to lift my baby yet and take a gander, but I typically see one that isn't monitored by an o2 sensor on cars and trucks and wondering if the pentastar might be an exception???

Thanks all!!

 

i think all single cats have upstream and downstream cats if its a true dual system it shod also but i think it may be a resonator and not a second cat

 

Okay. I don't wanna mess around with o2 sensor correction under warranty, but I always straightpipe the ones that dont affect tuning. My first mods will be intake/exhaust and I typically strip it down as far as possible to get the very most I can.
