    So I had the Magnaflow cat back exhaust installed on my 03, 2.7 liter.

    The check engine light came on the second day after the install.

    I took it back to where they installed it and the scanner said too much airflow in the cat.

    Has anyone had this happen?

    Would I have spend more money on a Magnaflow cat?

    Any help would be appreciated.

    Thanks for all you help.
