なんですか？これ。
左右の排気バランスをオンボードコンピュータで制御して、馬力・トルクなんかを調整するそうです。
05 のインジェクション車にしか付けられないようですが、もうここまで来るとバイクじゃないみたい。

The best of both worlds. This street-legal exhaust system provides the horsepower and torque characteristics of Screamin’ Eagleｨ Pro Race-Use Mufflers while maintaining EPA and CARB approved sound and emission levels. The catalyst-equipped exhaust system utilizes an electronic servo-controlled butterfly valve to alter the gas path between the left and right muffler. The integrated on-board computer measures operating conditions, and limits the exhaust flow to the left muffler to optimize performance, sound and emissions. The results are enhanced torque and horsepower throughout the operating range, and the rich, pleasing exhaust note you expect from a Harley-Davidsonｨ. The complete system includes left and right catalyst-equipped mufflers, servo motor, cable-operated butterfly valve, plug-in on board computer with service diagnostic capabilities, left-hand heat shield, and all necessary installation hardware.
