I am a big fan of 2-into-1's and use them as often as possible in my builds. We used Vance & Hines' FP3 to remap the ECM for both the Screamin' Eagle mufflers and the new 2-Into-1. The numbers on the Dyno are not from stock to the new pipe they are from the Screamin' Eagle mufflers to the V&H 2-into-1. Also the FP3 has a built in Autotune feature and this was not used to get these numbers, these numbers are from the map for the pipe available through the FP3. Stay tuned for the Autotune numbers, we will be riding around over the next few weeks with the Autotune enabled and after we finish we will re-Dyno and provide you all with the new numbers. All in all this was a fun project bike, Personally I am not a big fan of the Breakout because of the 240 rear tire, but the owner loves it, and after all the work we did on it and especially with the new pipe, I can say I am absolutely a fan, aesthetically at least.
