    May seem like a stupid question....

    Think I want to get a set of Gibson Stainless headers to pair up with my CAI and Gibson Dual Extreme Exhaust....

    Went to the website to purchase and had two options...

    With air injection
    Without air injection

    2011 5.3L Flexfuel......does it have air injection?
    I don't think it does....???

    Thanks!

    I would hope that there are no air injection ports in your exhaust! If my memory serves correctly, that is an old smog device from the 70's or 80's.
    It is a good Idea to have the headers with the Cat-Back. Don't forget to re-program the ECU!!

    That's what I thought...
    But when I entered in my vehicle information and those two options came up I second guessed myself :neutral:

    Thanks for the reply!
