Did you buy them from Autozone, or did you have Summit price match? Some folks here have had issues with availability and delays order directly from Autozone.
Ah bummer, I did buy them from Autozone. We'll see how it goes, they are being shipped 'directly from manufacturer'. I'm not in a hurry as I don't have plans to install these probably until Spring. But if I don't hear anything for a week or so I'll call and see what the deal is.
EDIT: I searched and found some threads where people had issues, looks like they were out of stock at the time and for some reason were charged before the headers were actually shipped. I paid online with my debit card and have been checking my bank account, no charges yet which my order said won't happen until the part is shipped. I'll still keep an eye on it and reach out if nothing happens soon.
