Came across these while surfing the 'net. I didn't know that RS*R was making exhausts in the U.S. anymore, but apparently they are going strong. (shows how much I keep up

)
They are supposed to be nice and quiet, which I want. The tip doesn't appear to be too huge, which I also want, but I can't find an exact size anywhere. Anyone know? Piping is 60 mm.
Just curious what you guys think about the Ex-mag series?
