02 sensors, egr valves, what are they doing?
#12
Our exhaust systems go like this: heads, exhaust manifolds, downpipe, cat, resonator, muffler/s. Resonator is NEVER a code word for the cat. If you remove the cat, you will need to get either an O2 simulator or a tuned PCM that ignores the second O2 sensor.

The "official" name is "O2 emulator". What it does is it fools the PCM into thinking that there is a rear O2 sensor that is performing perfectly fine. Here's one example of one: ZZ Performance
Even though it doesn't list any 5th gen Montes, I have one on my Monte and it's a 1998 so if you want one you will be okay. My O2 emulator is about 5 years old too, and it was cheaper back then too

It's not supposed to effect performance, but you will get a check engine light. If Minnesota has vehicle inspections then that will be a problem. And like I mentioned before, there are ways to get rid of the CEL.
