Screamin' EagleĀ® Active Performance Muffler Kit

The best of both worlds. This street-legal exhaust system provides the horsepower and torque characteristics of Screamin' EagleĀ® 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, soundand emissions. The results are enhanced torque and horsepower throughout the operating range, and the rich, pleasing exhaust note you expect from a Harley-DavidsonĀ®. 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. Mufflers are 49-state street legal when installed on fuel-injected motorcycles.

Anyone used this setup? Sounds sweet? I have been talking to my local tuner and he advises me to stay away from the true dual systems. Says I'll lose hp and torque also says to steer clear of the aftermarket computers. Even has the dyno charts to back his expert opinion up. With that in mind I am thinking of using these or the V&H Oval slipon's. I know they sound good

Anyone know how these sound?
