    Exhaust and Cold air intake mod STX 15F

    I was thinking about doing a cold air intake through the rear storage box and also doing away with the secondary muffler. What is the possibility of water ingestion if doing the cold air mod through the storage box? Would I see a significant improvement by doing these mods or should I just leave it alone?

    I did that on my 15F, cold air intake & single water box.... ZERO problem and ZERO performance gain.
    You will gain some space in the engine compartment though after removing the air box and the right side muffler.

    The way riva says to do it, with a small bottle jack, works fine.
