Rather than just spew vitriol, how about giving us the FULL story. Such as, did you buy the bike from a dealership or a private party? How much time passed between the purchase and finding the pipe failure? How old is the actual pipe? Did you contact the party that sold you the bike about the problem? Etc.
There may have been a known problem with the pipes, since you made mention of someone telling you yours was the updated version. Look into that and see if in fact you do have the latest version. If there was a known defect that led to a redesign, and you have the original version, perhaps that will change the response from S&S.
I don't know about you, but if I buy something used and "as is", as opposed to having a warranty, I don't expect a manufacturer to then take care of any subsequent failures. I would still be ticked off if it was clear there was a known defect, but at this point you haven't really made a case that that is the situation.
