Damn, sorry Falcon. Had I realized you were looking for a source I would have sent you to DMH immediately.
They make a great kit, and their customer service is top notch. In fairness, I have to disclose that I've gone thru 4 sets of their ovals on my Magnum, with the forth currently on the car and now leaking as well. The butterfly valve just wont stay closed, so it sounds like loose change rattling around under there.
But I sincerely doubt you'd have similar problems with the Raptor. You'd probably be positioning if much further down the pipe than my duals are, meaning you wouldn't have the same heat issues I do.
Of course Stainless Works would seem to be a great source too, although I have no first hand experience with them.
Hope that helps!
