Emissions testing.
So I bought a C5 with a check engine light due to the car not having any converters on it, so my question is how do you guys pass the test without having to put them back on and re working the exhaust system again. I believe all they do is just run the test through the OBD port. Im located in Chicago.

Make sure there no new trouble codes appears again, you should OBD monitors self-test run completely (you can verify it using a scan tool). This the only way to make your vehicles pass on the OBD II plug-in emissions test."

You need to find someone with an OBDII tuning software program. The rear O2 sensors can be "turned off" so the missing O2's won't turn on the SES light.https://www.corvetteforum.com/forums...2-sensors.html
