Hey Dill,
I've seen some on ebay from someone else. They have a bunch of them stacked on a pipe rack, looked like about 30 pair. Save some money and punch your own pipes. There is plenty of info here to guide you through it. I have a 3/4" hole through all plates and completely removed the rear two sets of baffles - 130 main jets and 3.5 turns out. I am slightly rich in the mid to upper throttle range so I will get some 128s to put in one day.
