Twistedarts,
While it is correct that no extended exhaust tee is available for the Legend (or Titan LX), the regular legend tee does a pretty good job of deflecting bubbles. It is one of the better that I have tried.
Mike,
The baffle you point out is simply a flat plastic piece that slides into a slot in the case. It really has little, or nothing to do with exhaust. I believe that it's primary function is, when the venturi is in the (+) position, to better direct the air from the air barrel to the mouthpiece. Of course, when it is in the (-) position, the venturi directs the incoming air away from the baffle and the mouthpiece.
