dc2rrrr, I thought you of all people would know that not all headers, cat's and b-pipes match perfectly. If Adrian suggested one and you decided to go it alone, why compain publicly? You didn't have to buy his cat anyway, just get the dimensions you need. It's just annoying when people publicly complain like this, because when I spoke to Adrian about getting a Toda header, the first thing he said was you need to make sure it will fit with your cat. I'm sure he would have done the same with you...
