Looking for 3-1-3 for 2011 Rocket 3 Roadster

Anyone know how I can get my hands on a 3-1-3 for my 2011? I've been looking at Maddog and Staintune, but from what I'm reading, Staintune won't work because of ABS and the Maddog's are next to impossible to find. I just dig the look of the 3-1-3 so if there are alternatives, let me know.

In USA btw but I'm willing to pay good money to get my hands on some nice pipes.
