SLP LM II Whistle?????????

I just installed a SLP LM II cat-back exhaust last night and it sounds great but at WOT there is a loud whistle. I have no idea what it could be. Is the resonator directional? It doesn't say anything about it in the directions. Do ya'll have any suggestions?

Um yeah I have the same issue, but it's only at the top of the RPM band but it definitely whistles a bit.

Doesn't bother me that much though as I don't drive around at WOT lol.

Would like to know the cause though

All stock except for the SLP LM II cat-back. The only other thing I can think of is maybe one of elements in the cats is broke up and lodged on the exhaust.
