Not trying to start an argument here and I'm not saying the Power Duals are not good but if you consider that they are duals, what are the Bagger Duals then? One is a 2-1-2, like the stock headers, which can't be considered true duals. The Bagger Duals are a 2-2 design with no merge between the 2 headers. Isn't this the real deal?
When I put my hands behind the mufflers (CFRs) on my 09, with the stock headers (no cat on the non-CA 09s), I feel much more pressure on the right side than the left, and much more heat too. I'd say 70%-30%. How are the Power Duals distributing the flow between the 2 sides? 70%-30% or 50%-50%?

Heat wise I am not sure that they would be better or worse than the stock header of the true dual as the real high heat is coming from the headers. The "X" is kinda in the middle.
Performance wise I can't comment on because I went from stock to a full out stage II setup.
My bitch with the power duals is the "X" pipe heat shield. It doesn't have a top side clamp and it rubs the chrome off the rear cylinder heat shield over time.
IMO and it's just that an opinion is that they may not be worth the coin over the stock headers. I wish that I had done the swap in stages to compare but I didn't. If it's performance that you want go to a 2:1. If it's that classic stereo sound that you are after then the 2:2 is the way to go. No matter what you do to get rid of the heat you need to open up the cans and the cleaner and get the bike tuned.
I know what you are saying about the heat on the stocker. When I first got mine waiting for all the parts to come in I actually pulled the dip stick a few times on hot days swearing that I was running it out of oil.

The Power Duals may be worth the coin for 2010 owners only because of the damn cat in the stock headers, but if I owned one, I'd have the stock headers cut open and the cat removed, like what Fulsac offers.
Much cheaper and as effective as aftermarket headers IMO and with the $ I saved, I'd buy cams.

Per V&H Tech, the split is 55%R/ 45%L. With a set of slip ons that are identical internally, the Powerdual X pipe helps over the stock head pipe because the stock headpipe is more like 60/40. I have dyno'd both set ups with only a 2 HP/ 3 TQ gain for the Powerduals. Not worth $400+ IMO. I know why V&H WON'T give or publish performance numbers now...
I have no cat, and the heat difference- well, I couldn't really tell. Maybe an infrared gun could be more factual. The installation is a PITA due to the shields. The tone is slightly deeper over the stock head pipe. HOWEVER, if you have a set of mufflers like the Jackpot Dyno Tuned slip ons on a stock head pipe, your grin will be wider than the Powerduals and Monster Oval set up. Most of the performance opportunity lies in the muffler. (throttle is crisper, response is better). To each his own, this is just my experience, I rather spend the $317 delivered for Jackpots than $400+ on the Powerduals and $600 on the Monster Ovals. That's cam install territory and more bang for the buck. The Powerdual look is though...

Now if only cams could reduce heat ...... <sigh>

My father just put Vance and Hines power duals, SE Air Cleaner, SERT, and Vance and Hines Hi Flow exhaust on his 2010 SE Ultra. It produced 97 HP and 111 ft lb of torque. It sounds amazing.
