A cat will help. I bought my car with RB header/presilencer and Apexi N1's. I replaced the presilencer with a high flow cat and it killed some of the resonance. One high flow cat is probably not going to be much more restrictive than a what you have on there anyway but it will lower the pitch just enough.

Have you ever looked at a catalitic converter? Its a brick with holes inside of a metal case with pipes on the end. I'm sure its more restrictive than an RB silencer and likely the XR-1 muffler too.
