sound like you have to retune your car since you change the exhaust system

Remember, some O2's use the manifold/header as the ground path for the sensor. Are your headers ceramic coated, or have anything on them that may affect the sensor ground? Just a suggestion.

Dont feel bad. My cars 6 months overdue. Just got temp tags and have to figure out how to quiet it down. If all your codes are throwin you prob need front O2's. The rears you can tune out or find some sims. Did you get the codes read specifically at like autozone ot did they print the DTC's at the inspection lanes?
