When starting up, it will first appear as a CEL then turn to service engine soon and on dash shows increased emission. Car is running great and did not notice anything wrong with it. Any solutions for this issue?

Like DrFerry said, you realize you need a tune to use this setup, correct?

Yes I do! Just didn't expect them to pop up this quick with a High Flow Cat Xpipe set up. Besides a tune is needed, will it hurt engine if keep driving?
