Looking for a bit of advice: just had a straight dual exhaust installed on my Vette with the third (back) cat removed and now the SES light has come on for the first time, although a week later.
Could both be related?

Why don't you pull the error codes before asking that question?

Because I have my code reader on order and wanted at least some up front advice from what I thought was a knowledgeable group, not a judgemental one...

Pull the codes with a paperclip and you won't have to wait. That's my up front advice. No judgment involved, just good advice. Knowledge is power. Knowing the codes will help you (and us) a lot.
