I think that I have responded to everyone via PM.
In response to someone's question about video clips, I have found that these three clips really do a great job of capturing what the exhaust sounds like:

I will admit that I did grimace a little in the one clip where the guy seemingly revved a cold engine and didn't do the Boxster chop when lowering his top. Oh well.
Also, if anyone is having trouble looking at the pictures, let me know and I will figure something else out.
