    Is this what you're referring to??? This pic is of my kook's stepped headers....I'm in Cali and yes that's an A.I.R. fitting. Hope that helps with what you're looking for.

    That is exactly what I was talking about now when you say AIR is it where the one way check valve would go or the egr

    If you've removed your egr equipment and aren't running it....you can get a block off plate for the AIR tube on the header.

    They shouldn't -- I have 1-7/8" Kooks race headers on our car and there are no fittings on the tubes. I was happy to see that it did come with a spare O2 bung on the collector for a wideband.

    that works too. I understand you want them on. that stupid backorder sucks. I'd do a blockoff plate since it's there. You never know how emission laws will change. but I wouldn't blame you for the cut and weld. Good luck!

    MASS sucks on there emision already I got a buddy that does the stickers so as long as he keeps his job I'll be good but if anyone else looks they will see the erg isn't there maybe I will just block it to be safe

    That's entirely up to you. It's already there so it'd be the wise decision considering the price of kooks but if you want the clean look..... Cut and weld.
