    With the open end cap, how many disks does it take to flow the core on these?

    On a stock 2012 ultra should the ECU be able to compensate if ran with no disks, no end cap and just the trim ring?

    As long as the O2 sensors are working properly the ECU should accomodate the extra flow.

    So, if i understand correctly, since they come with 10 disks they are already flowing at max and so If I just run with the trim ring only and no disks or endcap then it would still be flowing the same? If that is all correct then, which ever way I like the sound better shouldn't have any effect on flow(hence performance and ecu), right?

    In a general sense that is correct.
