    2008 15F has no secondary muffler

    I was thinking of getting the RIVA high flow exhaust kit....or the diy version in this forum section.

    As I read the instructions, and look at my ski, I realize I have NO secondary muffler. I have the primary, and the rubber hose to aluminum pipe that exits the hull.

    Does my factory setup flow as well as the Riva kit?

    Why did Kawasaki eliminate the secondary muffler?

    Is my primary muffler more restrictive than other models that have the secondary from the factory?

    I'm keen to know too as I wish to buy a rpm kit for my 2010 15f and was thinking I need the exhaust parts or would I be better off just buying everything else without those parts. Cheers trev

    are you sure you have a 15f and not just a stx? they are almost the same but there are a few differences. do you have reverse? a boarding step? which side does the exhaust exit on?

    if it is the 15f and not just the stx the exhaust exit should be on the same side as the header.

    mines an 08, and i have the second muffler, you must have an 09 as they deleted it that year, I think they deleted it simply to save money.

    thats weird then, to my knowledge the 15f only ever came with 2 waterboxes and the exit is on the same side as the header.

    here is a stx (its the same ski with a few things less than the 15f)

    here is the 15f (same ski but it has reverse and a boarding step.)


    the primary waterbox will be the same.

    I have a boarding step and reverse/

    Is the riva exhaust a waste of money, ad I do not have the second muffler?

    you have an 09..... your signature says so....

    Yep, its an 09. I should have read my signature for sure.

    So, DOES THE RIVA KIT EXHAUST KIT BENEFIT ME?
