awesome exhaust note

[supersporthc]

What kind of exhaust is this?  It's in portugese and all it says is that i's a black oval can.  I believe that this is the link.  If it's not search for "GS500 rs5" and see if anybody can figure out what exhaust that is.  It sounds awesome.  any help is appreciated.  Thanks
