Forget Bill's. A buddy wanted a CR pipe from them since FMF don't make a Fatty for the Cr500's anymore. I personally watched him call at least a dozen times to Bill's. He said he was calling 3-4 times a day for awhile. Noone answers, it's voicemail boxes that are unavailable. He talked to Bill himself, early on, and he is a One-man-band, but said he would make one. That was 2 months ago. I think he is busy with 4 strokes and quads or something like that.
