I've got a 3 inch catco myself, and a cheap ebay 4 to 2 to 1 header that fits inside the opening of the converter on the top and bottom. If the header's flange had been an inch more round it would have sealed with one gasket.
I had to get a friend to cut me out a 1/4 inch plate with a 2 inch opening that would seal to a 3 inch cat and used 2 gaskets until I go turbo and put in a 3inch downpipe too.
