AR Design Bombproof gasket failure

Has anyone experienced failure of their AR bombproof DP gaskets?

Six months ago when I got my LSD installed, the shop found my 2 year-old (10k-mile) gaskets had failed and so replaced them. Today while poking around under the car for an oil leak I found the new set had also failed.

My AR retailer suggests that "bombproof" is probably a bit of a misnomer, and that I should expect them to fail, though perhaps not as often as I'm seeing.

I contacted AR directly and sent pictures, but never received any response.

I know there's the possibility of an installation error, but to me everything looks kosher and unstressed under there.

I suppose I might also have clogged secondary cats, but my logs don't support that theory.

Any other ideas? Any better alternatives out there?

Thanks in advance.
