Slip ons for Night Rod

[blackdog]

I have a stock 2012 v-rod, night rod special. I am looking at some slip on mufflers #827-71134. How many discs will I need to run with it being a stock motor? I do not plan on a tuner right away, but had ST on my last 2 bikes and really like them. Thanks for your help.

8-10 discs with the closed end-cap (per muffler) was found to provide the best performance during R & D testing.

R & D refers to Research and Development. It is how we design and test systems to ensure real world performance.
