Question water box mod (Extra hole inside)
Question about the water box mod (Extra hole inside) on 15F
As the 2009 STX15X have just a single muffler( as the 2008 UltraX) is it recommand to do the exaust mod as per Riva Racing instruction free Flow Exaust (cutting the back and do the extra hole inside a get the cover weld) ?
If i do this mod will this give a noticeable improvement i mean RPM, speed gain, better acceleration? Will the jetski sound louder after ?

It will be louder. I did all my mods at the same time so I cant really say what the improvement was.

Not worth the trouble in my case. I noticed nothing except more noise.
