I got my Corsa Xtreme 3" Cat Back Exhaust System 21104BLK
insatlled yesterday on my 2022 LT1 Base C8 corvette and after driving it for 3-4 hours the check engine light came on.
Took it to see what codes it was throwing and it came up with P12EA & P12F5….they reset the CEL for me but popped up again after an hour of driving it.
any ideas or solutions I can get to fix this permanently going foward?
From Corsa's website: CORSA recommends installation of exhaust be performed by a professional. Due to GM Factory tolerances some C8 exhaust systems will require GM valve relearn sequence (valves should be re-calibrated according to GM Document ID 5406413) to mitigate a check engine light. See Installation Instructions for more details.
The valve relearn procedure has been documented and discussed on this forum in multiple threads. A quick search should turn up all the info you need to get it corrected.
