This was going to be my second suggestion...honest.

Here's a video of the sound i'm hearing. I couldn't find the source. I went under the car, felt around, started it and look and smelt around. Nothing.

Umm, I don't hear anything unusual there. It doesn't sound like an OEM exhaust, what is it running?

I guess I should have been more clear. I don't hear anything that would disturb me unless you said that it had a completely stock exhaust. What do you have?

He said it was oem. I definitely hear a whooshing sound in his vid and it's a little growly. I have the rsc36.

DOH!!! I missed that sentence in the third post.

That said, maybe you should try the Seafoam trick on jackstands. How long have you had the car? Has it always done this? I am wondering if one of your resonators or cats has packed it in.

Yep that's it. My problem is locating the leak if that's what it is. That way if I can't repair it, at least i'll save some money and time so the shop wont have to.

This is my second summer with the car. And yes, I believe it has always done this. Just hasn't really had my attention till now as I had to right the maintenance wrongs of the PO.
