ECM calibration

ECM calibration
Guys, I'm looking to change my 2010 FLHX 2 into 1 header. I want to use the HD 2 into 2 headers that HD put out this year. I have a pair of Rinehart slip on's given to me by a friend. HD catalog says the ECM will need to be re calibrated. I'm not changing the Air intake, it will stay stock.
Do I really need to re calibrate ?
Thanks, any help would be great. I'm searching the site for an answer.

Some found this to be a good answer, from another similar post.
Will you "need" a tuner? I don't know; what is your end state criterion for tuning? Most will say just a pipe, or just an AC swap, you don't need a tuner, but if you do them both you will need a tuner. I got the Twin Scan WEGO last winter, and then spent the whole year playing with the data logger and tweaking the power commander to tune my bike. Doing this myself, I learned more about tuning than I ever thought possible. It was very time intensive and downright aggravating at times. Once I endured the learning curve it was all worth it; my bike runs fantastic and is now tuned the way I want it, and I am very confident that my goal tune condition is exactly what the data-logger says it is. Bear with me, there is a point. Throughout this process I made a very fundamental tuning observation; that ANY modification to the intake or exhaust has an effect on the tune condition, just installing a clean air filter will alter the tune slightly. When someone else tells you a tuner isn’t needed, they are really saying your tune condition will remain “close enough” to the OEM or otherwise acceptable tune condition and that it wont really “hurt” anything. The question should be; are you willing to accept someone else’s perception of “close enough”? Knowing what I know now, NOBODY will ever convince me that they can accurately claim how a given map will perform. I tried several canned and “custom” maps from the most highly acclaimed tuning specialists in the country, and none of them proved to be remotely close to being “tuned”. Unless you have some type of AFR feedback you will not truly know the condition of your tune. So, your choices are; go with the recommendation of someone you trust, or do the mods and then hook up to some type of AFR reader to see for yourself if you actually “need” a tuner. Sorry I couldn’t give you a simple yes or no.

May I respectfully suggest you slide on over to the "tuning" section and read some the threads there before you "start" with the SE tuner?

Cool, I totally get the duals on a bagger. You know you want the symetrical look of the duals, now lets explore the other considerations for the exhaust. Do you want a stock pipe to maintain stock apearance? What do you want for "sound"? What do you want for performance? What are you willing to spend? Is the heat from your current pipe an issue for you?

Don't want to hijack the thread but I have a question for fabrik8r, I have an 11 SG with the 103 power pak, I would like to put a wimmer better sucker air cleaner, rhinehart 4 inch slip ons and from the reading I am doing here I am thinking a power commander and dyno run are in order for these mods, correct? I would like a bit more sound from the pipes, just a little more grunt, don't like stock air cleaner, like the looks of the wimmer better sucker.

I have a pair of Rinehart 3.5" slip ons. And I would like to use an HD 2 into 2 header set up with the CAT, maybe an AC. I'm thinking Xieds to help reduce the heat. I really don't want the expense of an HD SEPST and Dyno. Thought ?
