    removing the resonator

    would removing the resonator give it a deeper louder exhaust sound?

    any pros or cons?

    It does make a louder exhaust. More so at lower rpm. Not as much at wot over stock but is louder than stock for sure.
    The down side i have had with freeflow is the drone noise that it has at any throtle up to 4,500 rpm. It is also hard to hear if trying to talk while in wake zone but so are any of the exhaust mod setups.
    With that being said i like exhaust sound so i would not have the resonator in any of my skis with stock water box.
    Some have seen quicker throtle response without resonator, but I would not expect any rpm gain at wot.

    Glad this topic came up. No additional rpm's, droning sound. Seems like a loud waste of money!

    I installed mine last week, and it does sound good to me. The "drone" is there like they're saying, but I think it's just that the exhaust is so much louder in the low-mid than at WOT or higher RPMs. It does get pretty darn loud it you sit for a while at 3000RPM-4000RPMs, but only to the rider. To others is sounds good and exhausty .

    As for gains, I'm not sure. I will say that all I have power wise is the Free-Flow exhaust pipe (replaces resonator) and the 3" Riva air intake (not the 4" like a lot of people are going with for whatever reason). I am currently spinning a fresh 15/22R at 8100-8120RPM for the first 10-15 minutes of riding and then 8080RPMs consistantly after that in summer temps. When I had just the air intake and intake grate, people were telling me that the 15/22R would bring my RPMs down to around the 8000-8020 mark where it should be, yet I am still on the high end. This means that either the prop is off (but I did gain speed with it), or my ski is making more power. Could it be from the exhaust, I don't know.

    If you like exhaust sound and don't want to cut a 3 1/4 hole in your brand new ski, this is pretty much the only option (maybe install a shorty/modified waterbox with it).

    Some people have said they saw a 50rpm increase.

    The reason we are running 4 inch fresh air is there is no heat fade. MB last year I rode all day at 8100 rpm. You don't think it is hot and humid in Morgan City, La. in June. 8100 rpm when I first hit the water and 8100 rpm when I was done.
