SuperMeg disc recommendation needed

[rel3rd]

Bike is a 2000 Harley Davidson Softail Heritage Classic
Engine is 95" Zipper's "Muscle" kit, last dynoed at 97hp/101tq (with ThunderHeader)
Ignition is Dynatek TC88 adjustable curve module.
Carb is DaVinci modified S&S Super G, which seems to like it's 28 intermediate/78 main combo (.060" air bleed)

With ThunderHeader the bike lacks nothing as far as all around power. Has good low end, good roll-on power and very nice WOT.
No problems, hesitation or sluggishness revving right up to 6200 rpm's when asked to.

The Problem: TOO LOUD, even with 2 or 4 tabs of the baffle folded over.

Anyway, I have SuperMeg # 828-71572 on the way and am hoping that with some QUIET, I don't lose the good all around power I now have. Don't like the dyno, so just wondering what is the recommended number of discs for baseline?

16-18 discs should be in the ball park.

Thanks. That's what I'll try to start.
