i just installed of headers on my car, BUT the gasket included doesnt fit, wear can i get a 2 inch exhaust gasket? in miami, in florida in the southeast HELP>>>>

 

go to autozone and buy some gasket material, looks like thin cardboard, make your own with scissors

 

If it's the donut-style gasket, I wouldn't use a flat gasket. I tried that and shot two of them right off after a hundred miles or so. I got my 2" donut gasket from a Kragen auto parts. Just go to the parts counter of your local auto shop, and ask if you can look at the inventory of donut gaskets they have. Take measurements while at the store, and pop that ish on. It may not stick as far into the cat as the stock gasket did with the stock header, but it should create the proper seal.
