    Those open end caps are LOUD and would require a more rich mixture I'm sure.

    They are louder with open ends that is true. closed ends with all the disks gives more power and a higher pitched scream as rpm is increased. I have a 5 inch supertrapp 13 disks closed end on my 03 v-rod . tried with less disk open end etc . load as hell but less power. I
    like the mx3 x pipe on my zl9. may loose some hearing but like the high pitch sound myself.
