Need some input on noise - i-Club

I just put a 3" Invidia downpipe on my '04 with a Skunk2 cat back. All is well exept that I get a funky resonance sound coming from the downpipe / turbo area only between 3000 to 4000 rpm and only when I'm pushing it. Another way to describe the sound is something between a buzz and detonation. Nothing is loose and the heat heat shield is off comepletely (for now). All other rpm ranges seem great. Any suggestions?
