The Supersprint x-pipe that you posted looks different than what Supersprint has up on their site.
Although they list the following picture as a "' X - Pipe ' + Centre exhaust", which is only available through Hamann.
Edit: I just noticed that you pulled that picture from the NA site. Interesting that you can only get the X-pipe (granted a modified version) from Supersprint NA, but Europeans are pretty much forced to go to Hamann.
