First thanks to all who got this up and running again.
I have a 2015 103in with a stage 4 kit from SE installed by the dealer. It has an S&S head pipe and V&H twin slash slipons.
It has been dyno tuned for what it was worth. The noise is fine cruising but any throttle application it starts to bark loud.
My question is would a set of fat shots with the proper number of discs be louder and what would be the right number?
Would I lose power with them or stay the same. Really would like to quiet it down on acceleration.

Thanks for any input.
