Stock HD 103

So with the Screamin Eagale Fatshotz on this stock bike should i run it with the factory 10 disks or would you advise some other "better" combinaton? Like removing most of them? Per above. From a sound preference I really don't want it any quieter.

The pipes we build for HD are per their specs. Harley Davidson does some pretty extensive R & D work and I believe Harley's out of the box set up was found to be the best option for best all around performance and sound on a stock machine.
Can you tweak it by adding/removing discs? Sure; however fewer discs may lower the sound level.
