I installed the AirForce kit with the W/B pipe. I want to know what people have found out the best way to run the pipe. Mine came from Gary at SuperBike with the core, eight disks,end plate. It also came with another core - is that the quiet core and does that go first if want it quiter. I also heard people run the disks with no end plate. Is that right? If so do you run the core with the turn down nozel sticking out the end? Thanks for any info.
