    Default How many discs L&R

    I've got 2 Slash Cut Megaphone Slip On on the way. Just looking for a starting point for the number of discs for best performances (I like torque at the low RPM). I've been through most of the posts on this forum and I've got an idea but wanted to ask the experts.

    My bike is 2005 RK, stock 88" Injection with KN air cleaner, Fuelpack V&H curv FP-0133 and Andrews 26 cams.
    Thank you in advance

    7-8 discs (per muffler) is a good starting point for tuning.
