My '09 is running great with only the Rineharts.
Cycle World this month has an article where they put Monster Ovals on a Road Glide with no other changes. It picked up about 5HP and I'm sure the Rineharts would be about the same.

Yes, and NO
For the most part what you said is correct however most people overlook the following facts about flow and restrictions.

What facts about flow & restrictions did I "overlook"? Everything you said is just a longer, more in-depth version of the exact same thing I said earlier?
When you add after market pipes to your bike your essentially adding a larger "mouth" to your bike...your giving your bike a bigger place to release more air out of. This is not a restriction.
However, once you add this larger "mouth" to your bike your stock A/C now DOES become a restriction. It won't be able to efficiently take in the amount of air that your exhaust wants to expel. This is where you should add a "larger" A/C i.e SE A/C, big sucker, heavy breather...ect.
Your garden hose is filling up the bucket quicker than as if it had a nozzle on it example is true due to the fact of it's happy medium of factors- water pressure, air & size of hose. Each of these factors must efficiently compliment the other to all work effectively in unison. Now if you had a pressure of 110 gallons per minute coming out of that same garden hose then the hose itself becomes the restriction, like your stock A/C is with your after market exhaust.
My point is compensation. You've gotta make up at one end of the "air pump" what you've done to the other end; hence my mouse/elephant story (Ha!).

D&D Muffler just published an article in American bagger magazine where they took an 09 and added not only their slip on mufflers, but a high flow air cleaner too with absolutely no mods to the EFI and no download. They published the dyno chart and it seems to be normal all throughout the run. So?

"With just a wrench and a ratchet, every Harley-Davidson touring owner can be up and running within an hour. And this kit is designed so that you don't need a tuner upgrade. Just wrench and ride."
What do we do?

this subject has been around about as much as the oil threads .has anyone ever tried and could show on a/f or dyno chart what exactly does happen when you make these changes.i don't think the article in the magazine showed one to back up what they are saying.

I'll be installing my Stage 1 parts in another week or so, after my PC-V and a/c arrives from Fuel Moto. The "heat" issue is a big benefit of using a controller like the PC-V.

I believe in what D&D is saying and I belive that the 09s compensate nicely for the additions, in spite of what others may say. (It will compensate to run as stock) However, there is another issue at hand, seperate from the mufflers and exhaust issues and even at stock levels, the 09s run very hot. Thats why I finally decided to go the PC-V route, to help cool the motor dramatically by feeding more fuel.

Yes, the article is by D&D who is promoting their new "Boss" slip ons and they installed a "Zippers" brand high flow a/c unit. Nice HP and Torque gains, if I recall something like 5 HP and 7-8 Ft pounds of torque. The dyno run chart (air / fuel ratio) looked pretty flat across too.
