Get a 2-1 with a power commander III for the best performance. This will make a noticable difference in the way your bike performs and both are easy to install yourself or you can have it done.

You can find a great deal on the Power Commander Here.

You really oughta consider taking it to an experienced mechanic and checking into a Power Commander. If I wouldn’t have been fired I would’ve done it on my 2005 Harley Road King at work, but I had a feeling the Chief of Police would’ve been ticked off.
Everybody I know with a Power Commander raves about the power, check it out with some people, I don’t think you’ll be disappointed.
Any mods and exhausts changes you make will be better with this add-on too in my humble opinion.

Do the 2-into-1 for best results with your FLHR, the D&D is the best one available, grab that and a Power Commander (if you’re EFI) and you’ll be ready to rock…

I just don’t like the true duals b-cuz of that extra looped piece of pipe (its ugly, and a waste of space… and why send exhaust thru that whole extra curve anyways..)

The 2-1 exhausts like the Thunderheader or the Hooker Header produce the most H.P. of the pipes available. Both torque and H.P. are increased. I run the Hooker because it has a feature that is pretty cool, adjustable back pressure. What this does is allow you to tailor the tuning to the way you ride. P.S keep in mind you’ll need to play with jetting/ computor to adjust the fuel mixture to match the pipe.

Go two into one for performance. The author is right…..most people think Dual exhaust are the deal because of what they think they know from the automotive world but it isn’t the same. Even in the hot rod world, those in the know, use a crossover pipe on the duals to boost low end and mid range torque.

Your bike is huge and heavy and if you ride two up then you NEED TORQUE. A 2 into 1 won’t hurt the horsepower and will improve the torque dramatically.

true duels will boost performance but due to decrease in back pressure will requier remapping of your fuel curve . two into 1 looks kick ass and will also open up exhaust and gonna requier remapping almost any after market exhaust means you gotta remapp

two into one will help evacuate the exhaust out of the cylinder to get more good air fuel in. there for making more power. it this bike is efi you will have to get a program er to adjust for this.
