just did full exhaust on my 98 trans am.

BBk shorty headers
magnaflow cats and Y pipe
SLP catback.

Put everything together and SES light came on with those two codes.

Other than the headers and exhaust mods, only other mod is slp intake.

Does this sound like a tuning issue or maybe an exhaust leak is causing these codes?

Thanks for any input.
