    * It helps to develop backpressure in the exhaust system
    * It helps produce the tuning characteristics of the sonic waves that are produced in the exhaust system; amount of water introduced, tuning ect...
    * It helps with noise reduction

    I'm sure there are more, maybe someone else can chime in

    Did you also know that the 05/06 waterbox has 1 extra baffle, creates more backpressure, and is 1 decibel quiter than the 03/04 model?

    I disagree on the noise reduction. SMWs '00 with the 1300 EFI is wayyy quieter than his '05. That '05 was driving me crazy with a helmet on.(resonating)

    Jme, the info I gave came from the tech department at Yamaha U.K via a e-mail. It's straight from the horses mouth!
    Although, I will say my 05 at low revs has more of a 'grumbly' sound than my 04 ski, but wot, the 05 is quiter.Perhaps the noise test is like the emissions test. I.E, done at about 5500 rpm.
