I just did my own snorkel setup.
I was going to do the center snorkel, but I did not like the way everything was crammed in front of the handlebars, and the wires rubbing etc.
So I went out the sides through the removeable storage pocket pieces, since they only cost $15 a piece.
I have not gone through any water yet, since its 18 degress.
I can say one thing though, I think I gained a few horse power with the snorkel.
I took it out for a test run to see if I needed jetting.
In high gear from a dead stop, sitting on the seat, I wheeled it up high than I thought it would.
It used to not pull a wheelie without shifting some weight around, now its just sick low end power.
Not sure about the high end, I hope I did not loose any top end.
FYI, I used the 3" rubber fitting cut in half with a bushing from 3" to 2" and the rest 2" PVC.
Hopefully it does not leak! It would be an expensive $8000 leak... =p
I am still weary about driving my machine into deep water, even with a snorkel.
