    waterbox vs freeflow

    just wondering what are the advantages and disadvantages of each type? same level of sound? more horsepower?

    Free-flo for as little as......$8.....loud resonance in the low rpm range....no gain in hp.

    Waterbox.....don't know what the diy mod would cost....a box could be had for $300 and up...then you'd probably add a through hull for another $150 or so.....nice sound though....minimal gain in hp.

    I wanted to ask this question today.. Hp gain would it be better running a free flow (direct pipe out) or water box with a through hull?

    The free flow may give a little better throttle response and that's it. The waterbox and thru hull will net a small hp improvement.

    so what everyone is saying is that money can be spent on other mods for improvement first. i just thought with the air intake bringing in more air you also need to get rid of it faster. i personally prefer not to change my exhaust.

    For $8 DIY, or $30 (or how ever much) from Jerry/Riva at least do the free-flow. Decent sound, removes resonator box and cleans up the hull a little. The resonance at 3000 RPM is definitly heard, but seriously, how often are you at 3000 RPM? Me??? I am usually at idle (no wake zone), 6000 RPM (cruising) or WOT!

    EDIT: I can't find the short free-flow exhaust pipe in either store. I wonder if I will have one available in the next couple weeks when I go through-hull!

    I believe he meens no waterbox or shorty box. No waterbox will net gains. Problem is that its loud as a mutha phuca and it hits the rev limiter real damn quick. But if you like jumping waves and ain`t too old,,,,straight pipe is your ticket.

    Yes HOSS i mean a straight pipe ( no water box ) straight out through the hull. I'm not going to loos any power not having back pressure am i ? On a turbo, less back pressure the better and faster the turbo spools up but I'm not sure on super chargers all though they are both called forced induction.

    Thumbs up

    You are correct. And it doesn`t matter on na motors either. Its what back pressure represents. At 6g and above (any motor, any induction) ,,,,,let tha mutha breathe!
