CorkSport exhaust on MSP issues?

[Prohero]

i originaly got my CorkSport exhaust system for my n/a protege, but i just swappd it onto my speed protege. it was the catless power series exhaust, the fitment is all fine, however because i had no cats before id trip my check engine light. I solved this with the o2 sensor bung that i put on the bottom section of my headers, however my speed protege does not have a/m headers and my CorkSport exhaust has no inlet to plug the o2 sensor into where the facotry speed protege would have one between the first and second cat. Mainly my question is, by not pluging it into anything will my car run poorly, will i loose power by switching to the corksport exhaust?

You will have a CEL but the ECU only reads the primary O2 sensor for tuning. The secondary is only to test the cat. converter.
