You definitely should get a remap. Here's why...
The Harleys from the factory are very LEAN. They do that in order to pass the EPA emission standards. It's a somewhat artificial standard, because it mostly measures drive-by emissions at part throttle settings (typically 20 - 40% throttle). However, when you add a less restrictive slip-on, you increase the airflow. Net result? It's even leaner.
If you get an EFIremap, you will get a better running, cooler running, longer lasting bike that is far more responsive, is less prone to pre-detonation (pinging) and doesn't pop or backfire. If you go further and get a remap through either the Screaming Eagle Race Tuner (SERT) or Power Commander III (or many of the others), you will probably pick up 8-15 lb ft of torque and maybe 5 - 10 Hp, plus better economy. There are many excellent articles on this subject, including our very own Terry1955 here...

or Joe Minton at American Rider magazine, who writes about it on a very regular basis, but you could start here...

Believe me, it's worth getting it done right, otherwise you're only getting 80% of the bike's potential.

RE: help please!!!!!
Bagger before I installed my SE slip ons I started a thread on this exact same topic. I believe they ALL said with that exhaust only, no re- map was needed. I also called my dealer and asked them the same question. Same response, no remap needed..
Now if you increase the airflow by adding the stage one air thats a different story, you are increeasing airflow and will need to richen it up thus you will need some type of fuel management system whether it be a SERT, PCIII or whatever.

RE: help please!!!!!
I have this question in another thread. I took the Vance and hynes slip ons from my old 98 FLHTCI and put them on my 06 FLHTCI. I noticed a lot more back firing on decel and the bike running hotter. One dealer said I need to tune the bikeor I will burn the valves and in time ruin the engine price around $700( not the dealer I use ) andthe dealer I get my services done at, said I should not have to doanything because the 06 models have the o2 sensors in the headers. I would like a few opinions from you guys before I go $$$$ crazy !

RE: help please!!!!!
I just had Stage I, a SERT and true duals installed by the dealer - total cost $1700. So if you're just doing slip-ons, I'd cut $400 off of the pipes and $50-75 off labor, depending on what you buy.
