If your just doing the exhaust your fine as is. But mess with the intake and you WILL have to do something or risk overheating or damaging the engine from lean AF mixtures.

I had inquired about this same thing myself. I have an 08 rkc with stage1 and heavy breather.I was led to believe that if i went with true duals i would have to remap or add fuel mgt system.I recently added monster oval slipons since i knew i wouldnt have to do anything with this setup.Now i wish i didnt if what your saying i correct,i would of preferred True duals.

Frankly, I can't even say I'd try it. Sure, it'll run. But look at the shape differences in 3D graphs of the VE tables required for the EFI computer programming for stock and dual exhausts. These maps are from the last version of the SERT software and are base settings from which to be fine-tuned. Now the differences in the fueling these tables produce are not necessarily like night and day, but they're great enough to be worth the money spent on getting them into your bike's computer, and especially, fine-tuned for it.
OK guys, I'm gonna interject here a little. I've been reading these same posts for over 3 1/2 years here and here is my opinion (take it or leave it). Your bike runs like an EPA Regulated bike the way it is now. Why would you want it to run like that after putting on a $900 set of pipes. I'd tune my bike if I was gonna leave it stone stock. The Government is not gonna let Harley let your bike run the way you want it too. Go with the high flow air cleaner with your pipes and tune it correctly. It makes a huge difference.

If you just did slip ons no tune is required (optional) but if you eliminate the xover as in true duals a retune is required,you cannot run that configuration of pipes without risking damage to the engine you will have to get a reflash or some type of fuel management device.If you want to use those pipes you may as well get a high flow a/c to go with it sert or pwr commander,not sure if the dealer has a map they can flash for the combination that is cheapest way to go ,your doing no good at all with those pipes unless you retune and put on the a/c trust me you will not be happy with pipes alone,youll think you just lost power..Tom..

what if, you've changed the A/F and now put a different set of pipes from what you had mapped before?...in other words going from v&h to bubs or something...i think you then will have to remap it agian
