???I have an o4 busa with 7300 miles the person I bought it from has a full micron 4 into 1 system on it from what I understand he blew the micron out so instead of replacing it he had sombody make him a shortie with what looks like a muzzy pipe cut down. My ? is about the pcIIIr and how should it be working with this stupid setup . Today is the first time I looked at the at the pc I dont know what im looking at or how it works and what will happen if I unplug it ( also i noticed a small pin hole on the pipe would that affect the compression) everyones input would be greatly appreciated.
