Like others have stated.. The SMS header is the top of the line, they are made 1 at a time, not mass produced. So you would spend a pretty penny and wait quite some time before you get one.
IMO there are other options available for much less...
For example I picked up a JDM DC (w/2.5" collector) for my ITR for ~$270.
