Don't ask me , I didn't make them I just know that the 2 bikes have the same frame and headers so if they work on 1 they would work on the other. Last I heard they are not in production yet, they are waiting for enough orders to make it profitable. There is another thread with the prototype on the bike posted by the guys who made them.

I learned all I need to know about life by killing smart people and eating their brains.
