I just added the following edit to my original post in the section about the short bolts:

I took a look at the stock cats. The flanges on the stock cats are thinner than those on the Berks. So to be fair, Stillen is actually supplying the right size bolts because they're anticipating that their headers are going to be connected to stock cats. In other words, it's not so much that Stillen is supplying short bolts, but more the case that Berk is supplying extra long bolts because they know their flange is thicker. The only problem is that they're only supplying four, not six, because Berk is assuming that their HFCs are being hooked up to stock headers, not aftermarket ones.
