Some says its normal with thinner material used for aftermarket exhaust, but CSG mike's comment makes me confused too.
So I'm gonna take off header this weekend to take a look at the gasket.

I think the confusion here is that we have inconsistent/different descriptions for the sound. Deleting BOTH cats will result in a tinny, high pitched sound, but not a wooshing, "air leaking" sound.
Check the areas around the gaskets for leaks. If there are none, then don't worry about it
