I bought a car that has this ebay header on it and the downpipe gasket blew out... I emailed a couple of the sellers on ebay and they dont sell it seperate. It's the one cirlced in the picture, does anyone know where I could buy it?

 

Try to contact Bosal with the dimension.

 

ask scott if he still has that header I had on my old hatch

 

you can make your own. it comes in a sheet.

 

take it to your local parts store and try to match it up , some oem (toyota,mitsubishi,nissan) exhaust flange gaskets are made just like that.
