adding disks ( in general) increases HP at the detriment of Torque.
this is a balancing act.
the disk count i use when at home in the city and for canyons is aimed at torque.
MOST of our riding is at rpms below 3500 rpms
when i tour ( so long days at high way speeds) i add a couple of disks to each side (2/1/2) so as to increase HP...as the only time i am at lower rpms is at gas stops a few times a day.
and when i get to destination i may pull a few disks back off.
you need to find you own balance.
the open end cap is equivalent to 10 disks for flow...but louder than 10 disks.
so that is where your noise control comes into play.
all this is dependent on cat/ no cat- which are you?

Its nice to have a clean - crisp running bike and power is very subjective based on forum threads, replies. IMO there are very few fast HDs when compared to almost any sport bike even a 120/120 Harley at 800 lbs is a slug compared to a Ninja, Busa, GSXR etc and almost no amount of $ will change that.
Im happy with my Stage 1 103 on my RG, is it fast no, not compared to a lot of other stuff on the road but it runs better than stock and has passing power and enough to cruise all day at the speed I want. ill probably add cams soon but not so much for the power as just to mess with or modify something and if it adds a little seat of pants pull then great.
This is off topic Dyna J, what are you doing with your MGS TDs ? Were they black by chance ? Im in your area and might be interested in buying them for a change in looks.

you can idle watching tv on the sofa, but try running a 100 yard dash.
and your hp/tq comparo is not TD vs 2/1...but TD vs cat header
a distinction...I'm not trying to force you to make your bike the way I'd run mine, but you are not near comparing apples to apples

Having the cat in Jan and July are a big difference, wait until the summer and then decide if you think that cat gets hot!

An A/C and slip-ons (stage1) gives newer bikes about a 10% bump. Most comes from the A/C and tune as the cat breaks down the sound waves (quieter) without impeding flow greatly, allowing pretty open mufflers.
That said, I did notice a nice power gain and heat loss swapping my '09 non-cat header for a fullsac Xpipe. I am running Supertrapp SE Fatshoz with 19 disc and open caps after playing with different caps and discs. Really lost power with closed caps but my motor isn't stock.
As far as using all the power? Yes! When I want to pass, I pass. Riding sportbikes (or about any non-cruiser) makes it pretty clear how slow Harleys are. My bike dynoed at 109tq/99hp and it is good enough but I keep thinking, Headwork???

I have a heavy breather on my bike..power commander and tuned on a dyno. I really can't see my bike getting hotter than it was with the true duals..Ask 75% of the guys with MGS true duals they will tell you its to hot. The other 25% are lying..Even when they dyoned it they had the heat gun out trying to decrease the heat..On a stock pipe that's is tuned good the heat is no more than the MGS pipes...I'm talking about real world riding most guys NEVER get the true power out of their bike sound yes I agree the night stick is nemic..but I have a self esteem and don't need a "loud" bike..lol

well it's like trying to breathe holding a bottle cap in your teeth.

The cat does produce a lot of heat.
I am surprised you did not realize it when you had true duals.
I am using a cat less header on my street glide and noticed a difference in power over all, deeper and a shade louder sound.
Not saying you should, that is your decision to make.
I do not agree with you about engine heat.
All 3 of my HD's, super glide, wide glide and street glide are a lot less heat now than it did when stock.
My street glide would cook you
