Armytrix Armynator o2 Exhaust Sensor Check Engine Delete Module

This Armytrix Armynator module fits without modification into the original OBDII port to prevent the check engine light to turn on due to catalytic converter removal, O2 sensor disfunction, or any exhaust system modification. Easy to use, this electronic plug must be installed BEFORE the exhaust modification, as it is designed to avoid check engine signal but not to clear it once triggered.
