I just purchased a 2013 STI...It has Cobb intake, down pipe and custom exhaust...it has Cobb stage 2+ tune on Accessport...I’ve been driving it for a few days and all of the sudden the check engine light came on, the (S) light for the sport started flashing and so did the cruise light...the code on the Accessport was P0023 exhaust cam bank 2...could that have something to do with the fact that it pretty much has straight pipes or is it something more serious? Any input helps. I posted a picture of the Accessport code. I reset the Ecu and it goes away and then after awhile it happens again. I’ve read some things that says it could be an exhaust solenoid and some other things that said it could be an exhaust leak.
