The other one is WFO Performance one that Butler carries:

I can't find the original WFO website, interesting...
Yeah, some work with the RPM, and some can accept the victor. One I recall specifically requires the shaker to be mounted to the hood, forget which one.
PTFB makes one too, but uses a round type filter.
