Greddy Cat Back System 4 P10

Anyone have this on thier car? Can you tell me how it performs. If you have it how much did you pay? Where did you get it from and how much? Pictures anyone?

I have one. Did not buy it new so I have no idea what difference it made or how much it was. I really, really like the sound, agressive, without being too loud.

I have a few crappy pics of the Greddy starting here:
