    FZS Free Flow Exhaust vs Rear Exhaust

    I'm preparing my shopping list for the greenhulk store and saw that there were 2 options for the exhaust. What is the difference between the two....besides the cost? Does one give more performance gains? Which to choose?

    Im no pro at this but heres my .02$

    rear exit goes out the back of the hull and is out of the water (much louder)

    free flow goes out the same place the stock exguast does and is not as loud.

    I dont think there would be any proformance difference between the two, but both would be a proformance gain over stock

    hope that helps

    Thats what I was thinking. I had the free flow on my Ultra. I'll just go with that one.

    Rear exit requires holesawing your hull. lol

    I have the RIVA free flow and love it.

    The FF is plenty loud enough, I cant imagine how loud a rear exit exhaust would be. Doubt there is any difference in performance.

    ....

    performance gain = nothing
    but i have dual rear exit exhausts and they sound "orgasmic"
    they have a deep grumble and idel and a sound of sheer power while under higher rpms (it sounds like a offshore boat no s*it!) it turns heads and the sound alone make the ski feel as if it has 100hp more!

    you wont regret it unless your one of those ppl who actualy cares the sound might be bothering some misrible old fart on the shore lol

    Note the words under my name

    I have already been cautioned about noise on the lake I ride on.
    So I went to the other end of the lake....

    Wow!! It sounds that deep? I might be changing my mind. I have a few questions for you. You can only use the rear pipe setup or the
    free flow right? Not both?

    Is the rear exhaust setup complicated to install or can my local Watercraft Machanic do it?
    Thanks for the info in advance buddy!
