    Default How many 4" disc for 2 into 1 system

    Been running Fatshots on 1250 Vrod for awhile and love them, I now have a 2 into 1 system and adapted the end cap to fit the supertrapp disc off the fatshots,

    Question is how many 4" disc on a 4" muffler would be equal or similar to the V5 2 into 1 system with 12 x 5" disc with close cap

    Inlet diameter and core size make a difference in the amount of discs. I would consider starting your tune with 18 discs.
