I've already checked at most of the auto parts stores around here and can't come up with anything. I have the top gasket where the header connects to the head on there, and i'm buying a high flow cat soon that comes with the lower gasket, so now all i need is the middle gasket but i can't find anything. Might see about having one made somewhere. i'm way too cheap to buy a dc header, i got this one on ebay.
