Weird sound coming from trunk while under high RPMs

This only happens when I get on the gas. The noise won't be there and then I'll do a little pull and whenever I accelerate after that the noise is very apparent. It almost sounds like it's my Roush AB vibrating so much that it's causing something else to come loose and rattle. I've attached a link to a video I've uploaded. I think it could be something loose at the top of the rear suspension but I'm no expert when it comes to this.

Thanks in advance guys.

Have you looked underneath the car? I was having a hard time hearing it. Check your clamps and hangers.

Maybe a dumb question but have you looked in the trunk? Remove the carpet, check spare tire area? Certainly sounds like a reverb from exhaust vibration but what it is...? Pulling the rear seat and folding seat back down might help pinpoint where it's coming from.

There's no way to look under the car while driving it it's the only way to hear exactly where the noise is coming from. I've looked under and checked the hangers. Everything is in place fine.

Yes and yes that's why I feel like it has to be something with the right shock tower

Have you ever seen The Hangover? Check the trunk... you might have a small Asian man in there. Happened to me once... found a hooker in my trunk.

Well then, throw some duct tape around it and go for a ride! Maybe frog tape, easier to remove and no residue.

You can't get someone to rev your car while you look under?

It only makes the sound while moving.
